Answer:
3 electrons is contributed from each Nitrogen atom.
Total 6 electrons are shared in N₂.
Explanation:
- Nitrogen is belong to group VA
- it have 5 electron in its outer most Shell.
- it need 3 electrons complete its octet to become stable.
- Nitrogen have total 7 electrons.
- its atomic number is 7
The electronic configuration of Nitrogen is as:
1s², 2s², 2p³
it exist in diatomic form standard temperature and pressure.
Nitrogen form covalent bond and share 3 electron from each side.
total 6 electron are shared between 2 nitrogen atom.
For Covalent bonding it can share its 3 electrons.
