Is there a 200th element?
The periodic table of elements is a chart that contains all the known elements in the universe. It is divided into rows and columns, and each element is assigned a unique atomic number. But is there a 200th element?
The answer is yes, there is a 200th element. Polonium-200 atom is a polonium atom with an atomic number of 200. It is a radioactive element that is found in uranium-bearing ores and is typically found in minute amounts in nature. Polonium-200 is used in various industrial and medical applications and is also used as a source of neutrons in nuclear reactors.
What is the 150th element?
The 150th element is Schrodium, which is the provisional non-systematic name of a theoretical element with the symbol So and atomic number 150. Schrodium was named in honor of Erwin Schrödinger (1887–1961), who developed his equation for quantum mechanics.
Is element 140 possible?
Yes, element 140 is possible. According to this, Corbomite (Ct) is a chemical element with atomic number 140. However, in real-life science, element 140 has yet to be identified.

Oganesson is an extremely rare element, and is only found in trace amounts in nature. It is thought to have a half-life of around 0.89 seconds, and is believed to have potential applications in the medical and nuclear fields.
Is the Periodic Table Infinite?
The answer to this question depends on the definition of “infinite”. While there is no definitive answer, it seems likely that the periodic table is not infinite.
It is widely accepted that the periodic table represents all the known elements in the universe. As such, it is possible that new elements may still be discovered, but the number of elements is likely to remain finite.
It is also possible that the periodic table could be extended to include synthetic elements, or even theoretical elements. However, it is unlikely that these elements would ever become common enough to be included in the periodic table.
What is the 84th element?
The 84th element on the periodic table is Polonium, which is a relatively rare element. It is a member of the chalcogen family, which includes oxygen, sulfur, selenium, and tellurium. Polonium is represented by the symbol Po, and has an atomic number of 84 and an atomic mass of 208.9824.
What are the Properties of Polonium?
Polonium has several oxidation states, the most stable being Po(IV) in aqueous solution. This gives rise to its most important chemical property: its tendency to hydrolyse and form colloids of Po(OH)4, in analogy with most tetravalent elements. It also forms soluble salts with chlorides, acetates, nitrates and other inorganic anions, but precipitates with sulfides.
Where is Polonium Found?
Polonium is found in the pitchblende, which is a mineral ore that is composed of uranium oxides. The pitchblende studied by the Curies contained only about 100 micrograms (millionths of a gram) of polonium per metric ton of ore. The element can now be prepared artificially in a particle accelerator, or “atom smasher.”
What are the Uses of Polonium?
Polonium is used in the production of static eliminators, which are devices that are used to remove static electricity from machines. It is also used in nuclear power plants as a neutron absorber, and in the production of certain types of semiconductors. It is also used in scientific research, and has been used in the past to create a radioactive source for treating certain types of cancer.
What is the History of Polonium?
Polonium was first discovered in 1898 by Marie and Pierre Curie, who were studying the pitchblende ore. They were able to identify the element by its tendency to hydrolyse and form colloids of Po(OH)4, which was a unique property of the element. They named the element after their native country of Poland.

What is the 72nd element?
The 72nd element is called hafnium, and it has a rather interesting history and some important commercial applications. It is a transition metal, and is number 72 on the periodic table. Its name comes from the Latin word for Copenhagen, where it was first isolated in 1922.
A Complicated Discovery
The discovery of hafnium was rather complicated. Element 72 falls at the boundary between transition metals and rare earth elements, so it was not clear which type it would belong to. Some chemists thought it would be a rare earth element and searched for it among minerals containing rare earths, but without success.
The breakthrough came in 1923, when the Dutch physicist Dirk Coster and the Hungarian-Swedish chemist George Charles von Hevesy discovered hafnium in Norwegian and Greenland zircons. They analyzed the X-ray spectra of the samples and were able to identify the new element, naming it hafnium after Copenhagen.
Properties
Hafnium is a ductile metal with a brilliant silvery lustre. It has a very low level of absorption of neutrons, which makes it useful in the nuclear power industry. It is also used in the making of super-alloys, which are materials that are resistant to extreme temperatures and pressures.
Uses
Hafnium has a variety of commercial applications. It is used in the production of thermionic converters, which are used to convert electrical energy into heat energy. It is also used in the production of alloys for the aerospace and automotive industries. In addition, hafnium is used in the production of semiconductors, which are used in computers and other electronic devices.
Hafnium is a fascinating element with a long and interesting history. It has a number of important commercial applications, such as its use in the nuclear power industry and in the making of super-alloys. Its low absorption of neutrons makes it an invaluable material in many industries.
