In nature, nitrogen is reduced by nitrogenase enzymes, which contain large metalloproteins and promote a sequence of proton-coupled electron-transfer reactions to accomplish the reduction.

Nitrogen is a fundamental building block of ... Using the principle of electron flow conservation can better predict the outcomes of numerous chemical reactions that happen in waste water between ...

H has 1 outer electron. O has 6 outer electrons. The H circles must each overlap the O circle. Nitrogen molecules consist of two nitrogen atoms joined together. Nitrogen atoms can form three ...
