Shape Code

The shape and angle is controlled by minimising repulsion of the electron areas around the central ___ atom.
The electron arrangement that minimises repulsion for ___ electron areas is ___. This results in ___ angles.
Because ___ electron areas are bonding and ___ non-bonding, it results in a ___ shape.
