The VSEPR formula for a molecule of type AB₂E2 tells you that the molecule is made up of

• a central atom A, with two B atoms and two E atoms bonded to it.

• a central atom A, with two B atoms bonded to it and two unshared electron pairs.

• a central atom A, with two B atoms bonded to it by two bonding electron pairs.

• two central atoms B, with an atom A and two atoms E bonded to it.

Orbitals of equal energy produced by the combination of two or more orbitals on the same atom are called
