AX6 AX5E and AX4E2

Molecular Shapes (AX₆, AX₅E and AX₄E₂ Configurations)

Molecules in this category may have five, six or seven atoms. The configuration is specified as AX₆ for the case with seven total atoms, AX₅E for the case with six atoms and AX₄E₂for the case with five atoms. Remember the "E" represents electron groups that are not involved in bonding, the "X" atoms around the central atom and the "A" is the central atom. Molecules of the type AX₆are octahedral, molecules of the type AX₅E are square-pyramidal and molecules of the type AX₄E₂ are square-planar. Example AX₆ Molecules (Octahedral)
