Nonmetals tend to gain electrons to achieve stability, metals lose electrons, and noble gases are already stable with full valence shells.
Nonmetals are more likely to gain electrons to achieve a full outer shell, similar to noble gases. This is because nonmetals generally have 4-7 electrons in their valence shell and prefer to gain electrons to reach stability. On the contrary, metals tend to lose electrons to achieve stability. Noble gases are already stable because their valence shells are full.
