Question

can you please explain me the lewis structure of NO3- (nitrate)

Answer 1

Hello friend !!!

Here's the answer you are looking for

The number of valence electrons in nitrogen is 5. valence electrons in oxygen is 6.

2 of the oxygens form double bond with nitrogen and the third one forms a single bond with nitrogen.

As a result of which the octet of the 3rd oxygen it's not completed. So to complete the octet of the oxygen extra electron is added for which it gets a negative sign.

See the attachment for reference.
