Answer:
Nitrogen has
five valence electrons and each oxygen atom has six valence electrons.
Total valence electrons available
= 5 + 2 x 6 + 1 (negative charge)
= 18
The skeletal structure of \[NO_{2}^{-}\] is:
\[O\,\,\,N\,\,\,O\]
Total number of electrons needed by all the atoms to achieve
noble gas configuration \[=3\times 8=24\]
Thus, number of electrons shared = 24 18 = 6
i.e., there are three
bonds between the atoms.
