This is known as: Valence Shell Electron Pair Repulsion theory, or VSEPR theory. This theory is based on the principle that the valence shell electrons of each atom in a molecule arrange themselves in such a way that the inter-electronic repulsion is minimum, and the arrangement becomes stable. However, if two bonded atoms have the same electronegativity, then the bond pair electrons will be equally shared. Two outer atoms and one lone pair surround the central atom. First week only $4.99! When opposite charges are present on adjacent atoms, a bond can replace the charges. The central and outer atoms all lie in the same plane (molecule is flat).
