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

• covalent
• ionic
• cooperative
• lewis

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

• I am gaining 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
