1. 6.4 Covalent Bonding

2. Covalent Bonds
Covalent Bond - a chemical bond in which two atoms share a pair of valence electrons.
Covalent bonds take place in between non-metals.
Non-metals both need more electrons to fill their outer valence, so the only way to bond together is to share the valence electrons in each atom.

5. Molecules
Molecules - a neutral group of atoms that are joined together by one or more covalent bonds.
The positive protons in one nucleus attracts to the negative electrons of the other atom.

6. Multiple Covalent Bonds
Single Bond - when atoms share one pair of valence electrons
Double Bond - when atoms share two pair of valence electrons
Triple Bond - when atoms share three pair of valence electrons

8. Covalent Structures
Can be very simple two atom molecule or very complex lattices
Ex. O2, Diamonds (Carbon lattice)
