is directional, having a specific orientation in space between the bonded atoms.

The covalent bond is directional, having a specific orientation in space between the bonded atoms.

Valance Shell Electron Pair Repulsion theory is used to predict the shape of the molecules

3rd period or below may have 10 and 12 electrons around it

less then eight electrons around an atom other than H

• Resonance - two or more Lewis structures that contribute to the real structure

-

The best Lewis structures will have formal charges on the atoms that are zero or nearly zero.
