BONDING
Covalent Bonding
- Electrons are shared between non-metals

- To draw Lewis Dot Diagrams:\

-Add the valence e- in all atoms
-Identify which atom can form the most number of bonds (this is shown by the pairs that only have 1 electron). This will be the central atom
-Bonds between two atoms are repesented by a line.
-All valence levels must be filled, all electrons must be used


- Some compounds form more than one bond between two elements, they will make double or triple bonds
