• molecules have only covalent bonds • compounds can have either covalent or ionic

Covalent Bonds:  a bond between 2 non­metals.  • formed by the sharing of one or more electrons between atoms

Methane Gas: CH4

Carbon Dioxide CO2

Ionic Bond: a bond between 

a metal (cation) and a non­metal (anion) with opposite charges.

• a complete transfer of electrons•  characteristic of salts
