Nonmetals tend to

• gain electrons

• lose electrons

Metals tend to

• gain electrons

• lose electrons

If my charge becomes 2+ what does that say about me?

• I am stealing 2 electrons
• I am losing 2 electrons
• I am in period 2
• I have an atomic # of 2

If I gain electrons I become

• Positive because I've added to my atom
• negative because I've added electrons
• same because i'm balanced
• equal because now I have electrons

When metals bond with non-metals they form what type of bonds
