Review:Ionic Bonding and charge on ions

Today students learned about:
Covalent Bonding- Sharing of electrons(Non Metal+ Non Metal)

• Single Bond- Two atoms share one pair of valence electrons. Ex: F &F
• Double Bond-Two atoms share two pairs of valence electrons Ex: O &O
• Triple Bond-Two atoms share three pairs of valence electrons. Ex:N & N

Homework: With the help of the periodic table make 4 covalent molcule and show the bonding in terms of electrons.
