Chapter 9 Chemical Bonding I: PART 2

Chapter 9 Chemical Bonding I: PART 2. Ionic Bonding Model vs. Reality. Lewis theory: attractions btwn ions are strong ionic compounds should have high MPs & BPs (breaking down crystal should require lots of E ) stronger attraction (larger lattice E), higher the MP.

Covalent Bond

Covalent Bond. Covalent bonding. When atoms tend to attain octet arrangement by sharing , a bond will be formed between the sharing atoms . This type of bonding is called covalent bonding. 1. Sharing of one pair of electrons-Single bond 2. Sharing of two pairs of electrons-Double bond
