Answer 1

Answer: - 3

Explanation: As nitrogen has atomic number 7, we can write 7 as 2,5. Now, we know that each atom has shells and subshells. The first shell has 2 electrons and the subsequent shells try to get 8 (an octet) electrons. We need 3 electrons to fulfil the octet. But we lack 3 electrons. So put a '-' sign and then write it as -3.
