Any element with an atomic number greater than 10 is capable of hypervalency. Electrons in the valence shell of these elements can be placed into hybridized d-orbitals during bonding if it is necessary to reduce the formal charge on the central atom of a molecule.he elements in period 3 and above have d orbitals available for bonding which makes the expansion of the octet more likely. period 2 elements do not, the 2d shell has only â¦ s and p orbitals.
