Answer 2

Answer:

Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms).
