Also know, how many molecular shapes are there?
five
Similarly, what are the 6 basic molecular shapes?
Valence-Shell Electron-Pair Repulsion Theory
Number of electron groups | Name of electron group geometry |
---|---|
3 | trigonal-planar |
4 | tetrahedral |
5 | trigonal-bipyramidal |
6 | octahedral |
- VSEPR Rules:
- Identify the central atom.
- Count its valence electrons.
- Add one electron for each bonding atom.
- Add or subtract electrons for charge (see Top Tip)
- Divide the total of these by 2 to find the total.
- number of electron pairs.
- Use this number to predict the shape.
