H has 1 outer electron. O has 6 outer electrons ... so a triple bond forms between them. The structure of nitrogen is N≡N, showing that it has three shared pairs of electrons.

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.

Nitrogen-vacancy (NV) centers are atomic-scale defects in the lattice structure of diamond. They consist of a substitutional nitrogen atom adjacent to a vacant lattice site. NV centers have emerged as ...
