As3 plus. It is As3-
Se2- is incorrect the answer is As 3-
Phosphide is isoelectronic with argon.
Potassium is isoelectronic with the cation K+.
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
None. The Se2- ion is isoelectronic with Krypton.
