VSEPR

Postby AlexandraZuniga1L » Sun Dec 02, 2018 5:05 pm

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

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.)

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.

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.

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.
