Electron Regions Electronic Geometry Bond Angles
2 linear 180˚
3 trigonal planar 120˚
4 tetrahedral 109.5˚
5 trigonal bipyramidal 90˚, 120˚, and 180˚
6 octahedral 90˚ and 180˚
For NH3: N is the central atom.
Total valence electrons:
Group Valence Electrons
N 5A 1 × 5 e– = 5 e–
H 1A 3 × 1 e– = 3 e–
Total: 8 valence e–
Why is the H–N–H angle in NH3 smaller than the H–C–H bond angle in CH4? Why is the H–N–H angle in NH4+ identical to the H–C–H bond angle in CH4?
