Group 15 elements

The elements of group 15 are phosphorus, nitrogen, bismuth antimony, and arsenic. The most abundant element which is present in the air is nitrogen and the percentage of nitrogen present in the air is 78%. In the free state, the elemental nitrogen is present as diatomic gas (N2). In the organic matter obtained from plants and animals, phosphorus is the dominant element present. In nucleic acids, phosphate groups are present. Phosphates are also found in teeth and bones. The other elements arsenic, bismuth, and antimony are found as sulfides. Arsenopyrite, bismuth glance, and stibnite are examples of sulfides of arsenic, bismuth, and antimony respectively.
