The elements of group VA of the periodic table comprise nitrogen, phosphorus, arsenic, antimony and bismuth. Nitrogen and phosphorus of group VA show the typical properties of non-metals. For example, they are poor conductors of heat and electricity and give acidic oxides. Their compounds are predominantly covalent.
