Explanation:
- Atomic number of krypton [Kr] =36
- Electronic configuration of krypton [Kr] = [Ar]
- Common ions with valence electronic configuration of [Kr] are bromine ion, strontium ion, selenite ion and rubidium ion.
- The Atomic number of the following ions in increasing order are;
Se < Br < Rb < Sr
Se (Z) = 34
Br (Z) = 35
Rb (Z) = 37
Sr (Z) = 38
- Electronic configuration of the following elements are:
Se (Z) = [Ar]
Br (Z) = [Ar]
Rb (Z) = [Kr]
Sr (Z) = [Kr]
Therefore, the respective ions formed according to theabove electronic configuration are
Hence the two anions are
and, the two cations are
