Asked by lyne

list three ions that are iso-electric with potassium +1

please explain i have no clue
Answered by bobpursley
The number of valence electrons has to be the same. So in K+1, the number of valence electrons is zero (the electron in the outer has been removed, and the next electron configuration is 2s^2P^6. So Isoelectric ions include Ca+2, Ti+4
