Basically, electron pairs in a molecule want to adopt a geometry to maximize their distance apart, since like charges repel each other. For example, methane (CH4) adopts a tetrahedral arrangement - you can think of this as the carbon atom at the center of a pyramid and the 4 hydrogens at the four vertices. Bonds angles are 109.5 degrees. This is a case where all electrons are bonding electrons; they form the 4 bonds between carbon and hydrogen. Lone electron pairs also affect the geometry. For instance, water (H2O) has two lone electrons pairs; it adopts a bent/angular geometry.
