Read pages 158-164 p.164 #1-8 due Friday


Ionic vs Covalent Bonding

• Ionic: electron(s) leave one atom & gained by another atom to satisfy both atoms’ octets, this results in the formation of ions. The resulting opposite charges attract each other.

• Covalent: electrons are shared by two or more atoms to satisfy their octets.

How can you tell if a bond is IONIC or COVALENT?

• Easy way:

metals + metals = metallic bond

Nonmetals and Metals = ionic bond

Nonmetals + nonmetals = covalent bond

Properties of Covalent Compounds

1) Covalent compounds generally have much lower melting and boiling points than ionic compounds.

2) Covalent compounds are soft and squishy (compared to ionic compounds, anyway).

Properties, Cont’d

• 3) Covalent compounds tend to be more flammable than ionic compounds.

– There are exceptions to this rule!

• 4) Covalent compounds don't conduct electricity in water.


Draw the electron “orbits” for an atom of Chlorine.
