What are isotopes and isobars ?

Text Solution

Verified by Experts

Isotopes : The nuclei having the same atomic number (Z) but different mass numbers (A) are called isotopes.
E.g. : `._(8)^(16)O, ._(8)^(17)O, ._(8)^(18)O`.
Isobars : The nuclei having the same neutron number (N) but different atomic number (Z) are called isobars.
R.g. : `._(6)^(14)C, ._(7)^(14)N`.
