Why Can Phosphorus Form 5 Bonds - Web the outer d orbitals in phosphorus permit an expansion of the octet, which leads to the +5 state, with five actual covalent bonds. Web resulting in formation of 3 bonds with o. Phosphorus only 'needs' three more electrons to get a full valence shell of eight, but you'll notice. But in case of p4o10 one of the electron of 3s is excited to vacant 3d. Web as a member of the nitrogen family, group 15 on the periodic table, phosphorus has 5 valence shell electrons.
