The Periodic Table of Elements is an essential tool for scientists and chemists alike, allowing us to study and understand the nature of matter. But did you know that the number of elements possible may be capped at 137?
This prediction was famously made by Nobel Prize winning physicist Richard Feynman, who calculated that an atom with 137 or more protons would violate special relativity. This led to much speculation among the scientific community, with some jokingly suggesting that element 137, once it’s finally created, should be named Feynmanium – a fitting tribute to the man himself.
But is it really impossible for us to create element 137? Is there really a hard limit at 137 elements? The answer is a little more complex than a simple yes or no.
Physicists and chemists have long debated the issue, with some pointing out that Feynman’s calculation did not account for the size of the nucleus. When the calculation was repeated with this factor taken into account, the number was pushed up to 173. This led to some optimism that element 137 may indeed be possible.
However, quantum theories have since improved upon the Bohr model, suggesting that the maximum number of elements may actually be capped at Z < 173. While this has yet to be proven, it does raise the possibility that element 137 may remain a theoretical impossibility. At the same time, recent advances in nuclear physics have allowed us to create elements up to 117, with some suggesting that the newly recognized element 117 should be named Feynmanium in honor of the great physicist. In the end, whether or not element 137 is possible remains an intriguing question. To answer it, we must continue to push the boundaries of science and technology, exploring the realms of the unknown.
Is element 137 possible?
The periodic table of the elements, developed in the 19th century, has become a staple of chemistry and physics. It’s a convenient way to organize the elements and predict the properties of new ones that might be discovered. But what about element 137? Famous physicist Richard Feynman predicted an end to the Periodic Table, saying that an atom with 137 or more protons would violate special relativity. However, recent theoretical investigations place a limit on atomic size at Z < 173 or thereabouts, so the possibility of element 137 is still up in the air.
The Feynman Limit
Richard Feynman, a Nobel Prize-winning physicist, calculated that element 137 would be the end of the Periodic Table due to special relativity. He argued that the electron-proton repulsion would become too great, making the atom unstable. However, when Feynman’s calculation is repeated in a way that does account for the size of the nucleus, the number gets pushed up to 173.
In recent years, element 117 has been added to the Periodic Table. It was first created in a lab in 2010 and officially recognized by the International Union of Pure and Applied Chemistry in 2016. Martyn Poliakoff at the Periodic Table of Videos has proposed that this element should be named Feynmanium, respectfully making fun of the physicist for one of the few things he was wrong about.
Modern Theories on Element 137
Modern quantum theory has improved upon the Bohr model, and current theoretical investigations have placed a limit on atomic size at Z < 173 or thereabouts. It is possible that element 137 could still exist, but it would require more powerful tools than we currently have. Experiments that involve particle accelerators may be able to create elements beyond what we know today. Element 137 may or may not be possible, depending on which calculations are correct. We know that elements 99 and 100 were created more than 60 years ago, and 18 more have been created since then. So, it’s possible that element 137 could be discovered in the future, though the Feynman Limit may still stand. It would be interesting to see if element 137 could be created in a lab, and if it could, then it would be fitting to name it Feynmanium.
Can there be more than 137 elements?
The periodic table of elements is a cornerstone of modern chemistry and a crucial tool in understanding the behavior of matter. However, the question still remains: Is there a limit to the number of elements that can exist? Unbitrium (Ubt), also known as element 123 or eka-protactinium, is the hypothetical chemical element with the atomic number 123 and placeholder symbol Ubt. Calculations have shown that 326Ubt would be the most stable isotope, but can there be more than 137 elements?
What is the 146th element?
The 146th element is Promethium, or ~146~Pm, which is an isotope of mass 146. Promethium has the atomic number 61 and is a rare, silvery-white, radioactive metal. It is often found in uranium ores and is used in atomic batteries and other specialized applications.
Why can’t we make more elements?
The answer to this question lies in the underlying physics of the atom. According to the Bohr model of the atom, the electrons of an atom can only occupy certain energy levels. As the atomic number of an element increases, the electrons occupy higher energy levels, and the nucleus becomes increasingly unstable. This means that elements with an atomic number higher than 137 cannot exist because they become too unstable to exist.
Is there a 125th element?
Yes, there is a 125th element. It is called Tellurium and has the atomic number 52. Tellurium-125 atom is the stable isotope of tellurium with relative atomic mass 124.904425, 71.4 atom percent natural abundance and nuclear spin 1/2. This element is found in many minerals, including iron pyrites and copper ores.
Is element 123 possible?
At this time, element 123 is still hypothetical and has not been observed in nature. However, calculations have shown that it is possible for element 123 to exist and could be the most stable isotope. But since element 123 is still hypothetical, it is not yet known whether or not it can actually exist in nature.
The answer to the question of whether there can be more than 137 elements appears to be yes. While element 123 is still hypothetical, calculations have shown that it is possible for elements with an atomic number higher than 137 to exist. However, these elements would be extremely unstable and would likely not exist in nature.
In any case, the periodic table is an incredibly useful tool for understanding the behavior of matter, and it is exciting to think about how high it can go!
Why can there only be 137 elements?
It might seem like the Periodic Table is complete, with the addition of four new elements to its seventh row. But despite the discovery of elements 113, 115, 118 and 117 in the early 2000s and 2010, respectively, there are still no signs of elements 119 and beyond. So why is it that there can only be 137 elements?
The answer lies in a number known as “the magic number”, or 137. This number is significant in physics because it has popped up in many unexplained places. According to Nobel Prize-winning physicist Richard Feynman, the number 137 is the limit of how many elements can exist without violating the laws of relativity.
Electrons, Relativity and the Nucleus
At the core of the answer lies the behavior of electrons around the nucleus. Electrons move around the nucleus in a specific, organized way. This movement is described by quantum mechanics, which states that electrons can only occupy certain specific energy levels or “shells”.
The problem is that, for elements beyond 137, the electrons have to move faster than the speed of light in order to avoid crashing into the nucleus. This would violate the rules of relativity, which state that nothing can travel faster than the speed of light.
The Fine Structure Constant
Another factor that limits the number of elements is the fine structure constant, also known as alpha. Alpha is a fundamental physical constant that relates the strength of the electromagnetic force to the speed of light. It is equal to 1/137, and is thought to be the reason why the number 137 is so significant in physics.
The Future of the Periodic Table
Despite the fact that 137 elements are all that can exist without violating the laws of relativity, scientists are still searching for more. They are attempting to create elements beyond 137 by smashing together the nuclei of atoms in a process called nuclear fusion.
So far, they have been able to create elements with atomic numbers up to 118, but they are still unable to create elements beyond that. This is because the nuclei of atoms become more unstable with higher atomic numbers, making it very difficult to create elements beyond 118.
The number 137 is a special one in physics, as it is the limit of how many elements can exist without violating the laws of relativity. This is due to the behavior of electrons around the nucleus and the fine structure constant, which is equal to 1/137.
Despite the fact that elements beyond 137 can’t exist naturally, scientists are still attempting to create them through nuclear fusion. So far, they have been able to create elements up to 118, but they are still unable to create elements beyond that.
For now, the Periodic Table is complete up to 118, but who knows what the future may hold?
Is there a 127th element?
The periodic table is an organized arrangement of the chemical elements, generally arranged in order of increasing atomic number. As of April 2022, there are 118 elements that have been identified, but the list doesn’t stop there. Many scientists have hypothesized the existence of a 127th element, Unbitrium (Ubt).
Ubt, also known as eka-protactinium or element 123, has an atomic number of 123 and a temporary symbol of Ubt. Calculations have shown that 326Ubt would be the most stable isotope. But why can there only be 137 elements?
To Nobel Prize-winning physicist Richard Feynman, 137 was a “magic number”—it had popped up for no obvious reason elsewhere in physics. Feynman was so intrigued by the number that he calculated the precise value of 137, which is the fine-structure constant.
So, what is the 127th element? The 127th element is Tellurium (Te), with an atomic number of 52. Tellurium is classified as a metalloid and is a solid at room temperature. It is also notable for having an isotope of mass 127.
But what about the 128th element? That would be Trititanium (Tt), which has an atomic number of 128. Unfortunately, Tt has never been successfully synthesized.
What about the 126th element? The 126th element is Seaborgium (Sg), which has an atomic number of 106. It was first synthesized in 1974 and is named after the Nobel Prize-winning chemist Glenn T. Seaborg.
So, is there a 127th element? As of April 2022, synthesis has been attempted for every element up to and including unbiseptium (Z = 127), except unbitrium (Z = 123). The heaviest successfully synthesized element is oganesson (Z = 118), which was discovered in 2002. The most recent discovery is tennessine (Z = 117), which was discovered in 2010.
Despite the fact that we have yet to successfully synthesize Unbitrium (Ubt), many scientists believe that it exists and is just waiting to be discovered. Until then, the periodic table will remain at 118 elements. But with advances in technology and the help of dedicated scientists, the search for a 127th element may eventually be successful.
What metal has 125 neutrons?
Atoms are the basic building blocks of all matter. They are composed of three subatomic particles: protons, neutrons, and electrons. Protons are positively charged particles, neutrons are neutral particles, and electrons are negatively charged particles. All three of these particles have different masses, and it is the number of protons and neutrons in an atom that ultimately determines the mass of the atom.
Atomic Number, Symbol and Weight
When we look at the number of protons and neutrons in an atom, we refer to it as the atomic number. This number is represented by the symbol Z and is the number of protons in the nucleus of the atom. The atomic symbol is the symbol of the element, such as carbon or oxygen, and the atomic weight is the average mass of the atom.
Astatine – The Element with 125 Neutrons
Astatine is an element with an atomic number of 85, an atomic symbol of At, and an atomic weight of 210. It is the heaviest known halogen and is found in trace amounts in the Earth’s crust. This element has thirty known isotopes, which are atoms of the same element that have different numbers of neutrons. The most common isotopes of astatine are At-210, which has a negligible percent of natural abundance, and Am-211, which also has a negligible percent of natural abundance.
Neutrons in the Atom
When looking at the number of neutrons in an atom, we must take into account both the atomic number and the atomic weight. The atomic number tells us the number of protons in the nucleus, and the atomic weight tells us the average mass of the atom. From this information, we can calculate the number of neutrons in the nucleus by subtracting the atomic number from the atomic weight.
For astatine, the atomic number is 85 and the atomic weight is 210. This means that astatine has 125 neutrons in its nucleus.
What is Astatine Used For?
Astatine is a highly radioactive element and has no known uses in industry or commerce. However, it has been used in a few medical treatments and research projects. For example, astatine-211 has been used in the treatment of certain types of cancer, as well as in the diagnosis of certain diseases. It has also been used in some research projects to study the behavior of certain particles.

What element has 44 neutrons and 35 electrons?
Atoms are composed of three subatomic particles: protons, neutrons, and electrons. The number of protons and electrons are the same in a neutral atom, and the number of neutrons can vary. Therefore, the number of neutrons and electrons can be determined based on the atomic number and mass number of the element.
When it comes to determining the number of protons, neutrons, and electrons in an atom, the first step is to identify the atomic number and mass number of the element. The atomic number is the number of protons in an atom, and the mass number is the sum of the number of protons and neutrons.
For example, bromine has an atomic number of 35 and a mass number of 79. This means that there are 35 protons and 44 neutrons in the atom. As the number of protons and electrons are the same, there must also be 35 electrons in the atom.
But why is it important to know the number of protons, neutrons, and electrons in an atom?
Knowing the number of protons, neutrons, and electrons in an atom is important as it can help us to identify the element and understand its behavior. The number of protons determines the element, and the number of neutrons affects the stability of the atom.
The number of electrons also affects the stability of the atom. The number of electrons in the outer shell of an atom determines the reactivity of the atom. Atoms with full outer shells are more stable than atoms with partially filled shells, and atoms tend to form ions in order to become more stable.
What is an isotope?
An isotope is an atom of the same element, but with a different number of neutrons. Isotopes of an element can have different properties due to their different mass numbers. For example, the isotope of bromine, bromine-79, has 44 neutrons, 35 protons, and 35 electrons.
Knowing the number of protons, neutrons, and electrons in an atom is important to identify the element and understand its behavior. The atomic number is the number of protons in an atom, and the mass number is the sum of the number of protons and neutrons. The number of electrons in the outer shell of an atom affects its reactivity, and isotopes of an element have different properties due to their different mass numbers. Bromine-79 has 44 neutrons, 35 protons, and 35 electrons.
