Covalency of all elements
Did you know?
WebThe elements of group 15 generally exhibit -3, +3 and +5 oxidation states. The tendency to exhibit a -3 oxidation state decreases as we move down the group due to an increase in the size of the atom and the metallic character. Bismuth hardly forms any compound in oxidation state -3. In fact, the stability of the +5 state also decreases as we ... WebPhosphorus and the remaining elements can exhibit a covalency of five and a maximum covalency, also called expanded covalency of six. This is possible because of the presence of vacant d-orbitals in the valence shell. All the compounds of group fifteen elements, which exhibit a +5 oxidation state, are covalent.
