Solution

Isotopes: Elements having same number of protons e.g. atomic number but different mass number are called isotopes.
There are 3 isotopes of Hydrogen .They are Protium (₁H¹), Deuterium (₁H²) and Tritium (₁H³)

Isotones: The elements having same number of neutrons.
There are 3 isotopes of Hydrogen .They are Protium (₁H¹), Deuterium (₁H²) and Tritium (₁H³)
Isobars :Isobars are atoms of different elements which have same mass number but different atomic number.eg 40S, 40Cl, ⁴⁰Ar, ⁴⁰K, and ⁴⁰Ca:
