Question

write Lewis dot structure of Nitrate ion​

Answer 1

Answer:

There are one nitrogen atom and three oxygen atoms in the nitrate ion. Also there is a -1 charge on the nitrate ion. Nitrogen and oxygen are located at VA and VIA groups respectively in the periodic table. So nitrogen has five electrons in its valence shell.

Answer 2

Answer:

In nitrate ion, one of the oxygen shares two of its valence electrons, and forms a double covalent bond with nitrogen. ... Hence, none of its valence electrons are used in bonding and hence there are three lone pairs of electrons. The last oxygen forms a single covalent bond with nitrogen by sharing one electron.
