Distinguish between isotopes and isobars, giving one example for each.

Text Solution

Verified by Experts

Isotopes of an element are nuclides having same atomic number Z but different mass number A (or different neutron number N). Isotopes have identical electronic configuration and, hence, identical chemical properties.
`" "_(1)^(1)H, " "_(1)^(2)H, " "_(1)^(3)H and " "_(6)^(11)C, " "_(6)^(12)C, " "_(6)^(14)C` etc., are isotopes. Nuclides having same mass number A but different atomic number Z are called isobars. Isobars represent different chemical elements. In isobars number of protons as well as number of neutrons differ but total nucleon (or mass) number is the same. `" "_(1)^(3)H, " "_(2)^(3)He and " "_(6)^(14)C, " "_(7)^(14)N` are examples of isobars.
