In order to become stable, an atom will either gain or lose electrons. What must happen for a metal such as potassium to become stable?

gain electrons lose electrons share electrons nothing, metals are already stable

The atomic number of Potassium is 19. Potassium is an active metal. It is good reducing agent so we can say that Potassium will lose one electron to become stabel because the electronic configuration of K is 1s2 2s2 2p6 3s2 3p6 4s1 so here Potassium will lose one electron from 4s1 to become stable.

Potassium (K) (19) ELECTRONIC CONFIGURATION : 2,8,8,1

                            VALENCY IS ONE.

                           THEREFORE SINCE IT IS HAVING ONLY 1 ELECTRON  IT GIVES AWAY THAT ELECTRON . POTASSIUM IS A very reactive metal so. metals usually gives away electrons or they are said to be more electropossitive.

it loses electrons. it becomes a positive charge but loosing 1 electron therefore iy's valency is 1.
