Hydrogen – 1, Hydrogen – 2, Hydrogen – 3 are the isotopic forms of Hydrogen.Isotopic forms of Fluorine – Fluorine 17, Fluorine 18, Fluorine 19.Chlorine- 35, Chlorine – 37 are the isotopic forms of chlorine.

Isotopic forms of Uranium- U-235, U-238.

Isotopic forms of Oxygen – Oxygen -16, Oxygen -17, Oxygen -18.

Carbon-12 is the stable isotope of the carbon element whereas carbon-14 is the radioactive isotope. Therefore, the atomic number 6 of carbon in all the forms is constant. As discussed, atomic number is the unique property by which we can determine the element. The numbers 12, 13, and 14 represents the atomic masses of different isotopic forms of carbon. The number of neutrons in protium is zero, the number of neutrons in deuterium is one and the number of neutrons in tritium is two.Ĭarbon has three isotopic forms- Carbon-12, Carbon-13, as well as Carbon-14. All the three isotopic forms of hydrogen have the same number of protons but vary in the number of neutrons. Hydrogen has three most stable isotopic forms- protium, deuterium, as well as tritium. Thus, the definition “ Elements with the same atomic number but a different mass number are termed as Isotopes.” For Example The number of neutrons varies but the number of protons always remains same in an isotope of a single element. However, the number of neutrons can change. In a certain element, the number of protons will always remain constant. The number of protons and neutrons combined together is called atomic mass or mass number of an element, whereas the total number of protons gives the atomic number of an element.

These different varieties of the same element are termed isotope. The number of neutrons in both the varieties will be different. Elements or atoms are present both in radioactive and non-radioactive variety.

Thus it has a tendency to release subatomic particles to obtain stability thereby releasing radiation or energy in the process. Every radioactive atom will have an unstable nucleus. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons.Radioactivity is one of the properties of atoms. Atoms of an element that contain different numbers of neutrons are called isotopes. Neutral atoms have the same number of electrons and protons. Each atom of an element contains the same number of protons, which is the atomic number (Z). The atom consists of discrete particles that govern its chemical and physical behavior. To determine the number of neutrons in this isotope, we subtract 26 from 56: 56 − 26 = 30, so there are 30 neutrons in this atom. The 26 is the atomic number (which is the same for all iron atoms), while the 56 is the mass number of the isotope. Which indicates a particular isotope of iron.
