HOW TO DETERMINE IF ITS A COVALENT BOND OR IONIC BOND?

Do you have?:

*2 nonmetals?----------Yes(Click here)

*1 metal and 1 nonmetal?----------Yes(Click here)

*More than two elements----------Yes(Click here)

Special Rules:

*If H appears 1st, it is considered a metal.

*If H appears LATER, it is considered a nonmetal.
