Would Potassium Lose Electrons?

Potassium is in the first column and therefore has 1 electron in its outermost shell. It would tend to lose one electron and form a +1 ion.

Does potassium lose or gain electron?

K loses an electron so that it will have the same electron configuration as Ne. Since K loses one electron (1 negative charge) it is no longer neutral; it now has a +1 charge.

What happens when potassium loses an electron?

Transfer of electrons

This is not a stable outer energy level. When potassium forms a compound with iodine, potassium loses one electron from its fourth level, and the third level becomes a complete outer level. The potassium atom has become an ion.
