Isotopes are a type of atom that differ from each other in the number of neutrons present in the nucleus of the atom. They are variants of elements that possess the same number of protons and electrons, but a different number of neutrons. For example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.
In the atomic world, isotopes are very important. Since they possess the same number of protons, they have the same chemical properties. This makes them useful in a variety of applications such as medical imaging, food safety, and industrial processes.
Isotopes are divided into two categories: radioactive and stable. Radioactive isotopes are unstable and emit radiation as they decay. Stable isotopes do not emit radiation and are used in a variety of research and applications.
In this article, we will discuss the importance of isotopes, the different types of isotopes, and some examples of isotopes. We will also provide a few examples of isotopes to help us understand them better.
Atoms are the building blocks of matter and isotopes are an important part of the atomic structure. Isotopes are variants of an element that have the same proton number, but differ in their neutron number. This difference in neutron number results in different physical and chemical properties. For example, carbon-14 is radioactive while carbon-12 is stable.
Isotopes are used in a variety of applications such as medical imaging, food safety, and industrial processes. They are also used in research to study the history of the Earth and its environment.

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. They can be found naturally in the Earth’s crust. In order to understand what isotopes are, it is important to have a basic understanding of the nucleus of an atom.
Atoms are composed of protons, neutrons and electrons. The protons and neutrons make up the nucleus of the atom, while the electrons orbit around it. The number of protons in an atom is what determines the element, while the number of neutrons defines the isotope.

Parent and Daughter Isotopes
When a radioisotope undergoes radioactive decay, the starting isotope is called the parent isotope. Decay produces one or more daughter isotopes. For example, uranium-238 is the parent isotope that decays into the daughter isotope thorium-234.
Isotope vs Nuclide
An isotope refers to a sample of atoms. All atoms of an element have the same atomic number but may have different mass numbers due to a difference in the number of neutrons in their nuclei. A nuclide is an atom in an specific state. It can be described by its mass number, atomic number, and energy state.
Hydrogen-1, Hydrogen-2 and Hydrogen-3
Hydrogen-1 (protium), hydrogen-2 (deuterium), and hydrogen-3 (tritium) are isotopes of hydrogen. Hydrogen-1 is the most common isotope and makes up 99.985% of natural hydrogen atoms. Hydrogen-2 and hydrogen-3 are both unstable and are used in nuclear reactions.
Comparison between Isotopes and Isobars
An isotope is a variation of an element that possesses the same atomic number but a different mass number. A group of isotopes of any element will always have the same number of protons and electrons. They will differ in the number of neutrons held by their respective nuclei. An example of a group of isotopes is hydrogen-1 (protium), hydrogen-2 (deuterium), and hydrogen-3 (tritium).
Isobars are atoms that have the same mass number but different atomic numbers. They are not isotopes, but they are both atoms of different elements that have the same mass. An example of an isobar is carbon-12 and magnesium-24.
In conclusion, isotopes are atoms with the same number of protons but different number of neutrons. Carbon-12, carbon-14, uranium-238, thorium-234, hydrogen-1, hydrogen-2, and hydrogen-3 are all examples of isotopes. Isotopes are different from isobars, which are atoms with the same mass number but different atomic numbers.
What is an isotope example?
Isotopes are variants of a chemical element that have the same number of protons and electrons, but a different number of neutrons. In other words, isotopes are different forms of the same element that differ in their nucleon number. As an example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.

The terms related to isotopes are isotope (noun), isotopic (adjective), isotopically (adverb), and isotopy (noun).
Parent and Daughter Isotopes
When radioisotopes undergo radioactive decay, the initial isotope may be different from the resulting isotope. The initial isotope is known as the parent isotope, while the atoms produced by the reaction are called daughter isotopes. There may also be more than one type of daughter isotope produced.
As an example, when U-238 decays into Th-234, the uranium atom is the parent isotope, while the thorium atom is the daughter isotope. The atomic mass of carbon is determined by the average atomic masses of its isotopes as well as the abundance of each isotope.
Types of Isotopes
There are two main types of isotopes: radioactive isotopes and stable isotopes. Stable isotopes have a stable combination of protons and neutrons and therefore have stable nuclei. They do not undergo decay and do not pose any danger to living things, unlike radioactive isotopes.
Radioactive isotopes, on the other hand, are unstable and undergo decay. They emit radiation or particles and are extremely hazardous to living organisms. Examples of radioactive isotopes include uranium-238, strontium-90, and cesium-137.
Uses of Isotopes
Isotopes have a wide range of applications in various fields. They are used in medicine to diagnose and treat diseases, in agriculture to determine soil fertility and crop yields, and in geology to study the age of rocks and fossils. They are also used in industry to detect leaks in pipes and to measure the thickness of materials.
In addition, isotopes are used in research to study the structure of atoms, the behavior of particles, and the properties of matter. They are also used in nuclear power plants to generate electricity and in nuclear weapons to create explosions.

What are 5 radioactive isotopes?
Radioactive isotopes are unstable atoms that emit radiation in order to become more stable. They are created through nuclear reactions, either naturally or artificially, and can be used for a variety of applications. Here are five of the most common radioactive isotopes and their uses:
