Isoelectronic means having the same amount of electrons, so Kr is isoelectric with Br.
As3 plus. It is As3-
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.
Methyl carbocation (CH3+) is isoelectronic with borane (BH3).
