Metals loss electrons and nonmetals gain electrons.

Nonmetals usually accept electrons to become negative ions (anions), e.g. Cl + e- --> Cl-.
Atoms of non-metals usually gain or share electrons when they react with other atoms.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
Nonmetals gain electrons.
Metals loss electrons and nonmetals gain electrons.
They tend to gain electrons when reacting with a metal. Metals generally are short of a full octet by 1 to 4 valence electrons. It is easier to drop 2 electrons than try to gain 6 electrons. The elements in group four can go either way, but the other metals will give up electrons, and non-metals will take them.

nonmetals tend to gain electrons when they react
This happens when nonmetals react with metals. It is easier to gain 2 or 3 electrons than to lose 5 or 6 from their valence shell anion - negatively charged
