COVALENT BONDS.notebook April 26, 2011 WHAT IS A COVALENT BOND? H C H l H A covalent bond is when atoms share electrons. O O Mar 19­7:45 AM 2

COVALENT BONDS.notebook April 26, 2011 What type of elements form covalent bonds? • Covalent bonds often occur between nonmetals. • In a covalent bond, both atoms attract the shared electrons at the same time. Mar 19­7:45 AM 3
