(i) Identify that which of the following pairs are isotopes and which are isobars? Give reasons for your choice.
(ii) Do isobars also have identical chemical properties like isotopes? State reason.
(i) A and B are isobars as they are atoms of different elements having the same mass number.
X and Y are isotopes as they are atoms of same element (same atomic number) having different mass numbers.
(ii) No, isobars do not have identical chemical properties because they have different atomic numbers as well as electronic configurations.
