4. valence electrons
1e-
7e-
8e-
3e-
4e-
5e-
6e-
2e-

5. When filling in valence electrons, fill electrons in individually then pair them up.
Br has 7 valence e-
6 nonbonding electrons Br
Bonding electron

6. Cl H F O N C Electron Dot Diagrams Valence Lone Bonding
Electrons Pairs Electrons Cl H F O N C

7. Electron Dot Diagrams for Ionic Compounds
CaF2 - - F F
F has configuration 2,7 2+
Ca has configuration 2,8,8,2 Ca
Ca gives an electron to each Fluorine
[ ] F - Ca 2+
[ ]
Ca has a full shell of 8
We always put brackets around all ions
