VSEPR

[AlexandraZuniga1L]

When theres three atoms and one lone pair would the VSEPR formula be AX3E?

[Krisdylle Repollo 4H]

Well one of those three atoms would have to be the central atom (A) so technically the VSEPR formula would be AX2E. (A = central atom, X = atoms attached to central atom.)

[Kate Chow 4H]

I'm not exactly sure what you mean by atoms, but when there are 3 bonds and 1 lone pair, the VSEPR formula is AX3E.

[janeane Kim4G]

If you mean one central atom connected to two other atoms, the VSEPR would be AX2E. That means there are 3 regions of electron density, including the lone pair that you specified. However, if you mean 3 atoms by one central atom connected to 3 atoms with a lone pair on the central atom, then the structure would indeed be AX3E like you specified.

[Fionna Shue 4L]

If there is a central atom that the three atoms and the one lone pair is attached to, then the VSEPR formula would be AX3E. A is the central atom, X3 represents three atoms attached to the central atom, and E represents the one lone pair attached to the central atom.
