The redox reactions affect the number of covalent bonds that a carbon makes to a heteroatom substituent, such as nitrogen and oxygen. Each redox state of carbon (Fig. 2) is associated with a class ...

Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. The structure of nitrogen is N≡N, showing that it has three shared pairs of electrons.
