Electron Geometry is the simplest system for geometric shapes. 

Electron Geometry

Concept #1: Electron Geometry

The electron geometry of a compound treats surrounding elements and lone pairs on the central element as the same.

Example #1: Determine the electron geometry for the hydrogen sulfide molecule, H2S.

Practice: Determine the electron geometry for the carbon disulfide molecule, CS2

Example #2: Determine the electron geometry for the following molecule: CH2O.

Practice: Determine the number of electron groups for the following cation: AsBr2+.

Practice: Determine the electron geometry of the nitrogen atom within methylamine, CH3NH2.
