Ionic Compounds

Metals tend to 

• gain electrons
• lose electrons

Nonmetals tend to 

• gain electrons
• lose electrons

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

• covalent
• ionic
• cooperative
• lewis
