Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base. Only two 5-carbon sugars are found in nature: ribose and deoxyribose.
Nit rogen is a non-metal. A nitrogen atom has 5 electrons in its outer shell. Nitrogen is in group 5 of the periodic table. Two nitrogen atoms will each share three electrons to form three covalent bonds and make a nitrogen molecule (N2). This is a picture of a nitrogen molecule.By sharing the six electrons where the shells touch each nitrogen atom can count 8 electrons in its outer shell.wo nitrogen atoms will each share three electrons to form three covalent bonds and make a nitrogen molecule (N2).
