- Bonding shapes
- Linear
- Two bonding pairs of e- around a central atom
- 180 degrees
- Trigonal Planar
- Three bonding pairs of e-
- 120 degrees, all bonds in the same plane
- Tetrahedral
- Four bonding pairs of electrons
- Three dimensional, bond angles of 109.5 degrees
- Trigonal Bipyramid
- Five Bonding pairs of electrons
- Bond angles of three electron pairs 120 degrees
- Bond angles of 90 degrees for two electron pairs in other plane
- Octahedral
- 6 bonding pairs of electrons
- 90 degree angles between pairs
- Square Planar
- 4 bonding pairs of electrons and 2 lone pairs
- Bond angle of 90 degrees
- LONE PAIRS
- For every lone pair, subtract 2.5 degrees of original angle
- Linear
