It gives the number of isotopes which an element has, their relative abundances and masses. Isobars are the atoms of different elements having same mass number but different atomic numbers. Isobars are nuclides of different elements that have the same mass number (same number of nucleons). In the nucleus of atom of isobars the number of protons are not equal. Iron and nickel have atomic number 26 and 28 respectively. The term isobar is derived from the Greek word isos, meaning "equal" and baros, meaning "weight". 20Ca40, 18Ar40, both have same atomic mass number and have different atomic numbers. Isotopes have different numbers of neutrons but a similar number of protons while isobars have the same number of protons and neutrons in total, but different numbers of protons individually. Alfred Walter Stewart in 1918 suggested the term isobars. Mass Number: The mass number is always a larger value than the atomic number. (c) Isotones are the species having same number of neutrons.

Atomic number and mass number are fundamental details about an atom. All three of them have the same number of protons, but the numbers of neutrons differ. Since isobars have the same mass number, therefore sum of the protons and neutrons in the nucleus of each is the same. (ii) they have same number of electrons but different number of neutrons. Isotopes are atoms with the same number of protons but differ in numbers of neutrons. (5.8.8) number of neutrons = 65 − 30 = 35. Why ? e.g. Eg :- Calcium (Ca) - atomic number - 20 and Argon (Ar) - atomic number 18 have different atomic numbers but have the same mass numbers - 40.
