Basic purpose of this lecture is to discuss on the Nitrogen Group. Nitrogen and phosphorus are required by living things and are used to manufacture various items. These elements also are parts of the biological materials that store genetic information and energy in living organisms. This group consists of the elements nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and perhaps also the chemically uncharacterized synthetic element ununpentium (Uup). Although almost 80 percent of the air you breathe is nitrogen, you can’t get the nitrogen your body needs by breathing nitrogen gas.
