The size of a phosphorus atom also interferes with its ability to form double bonds to other elements, such as oxygen, nitrogen, and sulfur. As a result, phosphorus tends to form compounds that contain two P-O single bonds where nitrogen would form an N=O double bond.Nitrogen forms the nitrate, NO 3 - , ion, for example, in which it has an oxidation number of +5.he chemistry of nitrogen is dominated by the ease with which nitrogen atoms form double and triple bonds. A neutral nitrogen atom contains five valence electrons: 2 s 2 2 p 3.
Alpha amino acids have the -COOH and -NH2 groups both attached to the same carbon atom, called the alpha carbon atom. The simplest amino acid, which is the molecule glycine, H2NCH2COOH, contains no asymmetric carbon atoms (tetrahedral carbon atoms with four different groups attached). All of the other amino acids do contain such a carbon atom and are therefore optically active.
