Down
- 1. By rotating the unpaired dots in the electron dot notation for two chlorine atoms, the single dots can be shown forming a bonding pair
- 2. attraction between metal atoms and their sea of shared electrons
- 4. Molecules made of two atoms, whether of the same element or not
- 6. An electrostatic attraction that forms between two atoms when they share or transfer valence electrons
- 7. Opposite electrical charges on these ions attract each other
- 9. Atoms are generally most stable when they have a full eight electrons in their valence energy level
