• 8

Elements that have 1, 2, or 3 valence electrons tend to

• lose their valence electrons
• gain enough valence electrons to have 8
• not gain or lose any electrons

Elements that have 5, 6, or 7 valence electrons tend to

• lose their valence electrons
• gain enough valence electrons to have 8
• not gain or lose any electrons

Atoms with a +3 charge have 

• gained 3 electrons
• lost 3 electrons
• gain 3 protons
• lose 3 protons
