Molecular Shapes and VSEPR Theory
When atoms bond together in a compound they do so by maximizing the distance between their bonding electrons. Together these bonding atoms form a Lewis Dot Structure and 2 different geometries can be used to explain its shape. The first geometry known as the Electron Geometry is seen as the idealized or orbital shape. The second, more accurate geometry known as the Molecular Geometry pays closer attention to the repulsive effects of the electron lone pairs.
