Problem
The following questions explore how the numbers Z, A and N influence chemical and nuclear behaviour.
(i) Explain why two isotopes of the same element exhibit identical chemical properties but may differ in nuclear stability.
(ii) Justify why two isobars generally possess different chemical properties even though their binding energy per nucleon may be comparable.
(iii) With one suitable example each, describe how isotones help scientists investigate the role of neutron number in nuclear properties.
