VSEPR Notation

[ngarcia]

Do the numbers accompanying the A, X, and E depend on electron pairs or individual electrons?

[Rohan Kubba Dis 4B]

A refers to the central atom, X refers to the number of bonds and E represents lone pairs. However, just remember when you have a radical, you treat that lone electron like a loan pair. So, essentially, E usually represents lone pairs of electrons, however it is important to note that radicals are treated the same as lone pairs when finding molecular geometry

[katrinawong3d]

A refers to the central atom, X refers to the number of bonds, and E refers to the lone pairs.

[Nathan Nakaguchi 1G]

Usually A will not be accompanied by a number as it represents the central atom of the molecule. Whatever number follows X represents how many atoms are bonded to the central atom A. The number that comes with E represents how many lone pairs there are on the molecule's central atom.

electron pairs

[Maya Gollamudi 1G]

A is the central atom, X's subscript refers to the number of bonding electron pairs around the central atom, and E's subscript refers to the number of lone electron pairs on the central atom.
