Also know, how many molecular shapes are there?

five

Also Know, what are the 5 basic shapes of molecules? Molecular Geometries. The VSEPR theory describes five main shapes of simple molecules: linear, trigonal planar, **tetrahedral**, trigonal bipyramidal, and octahedral.

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 |

How do you identify a Vsepr shape?

- 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.
