<h3><u>Answer;</u></h3>
Nitrogen (N)
<h3><u>Explanation;</u></h3>
- Atoms may lose or gain electrons to achieve stability. Metal atoms lose electrons to attain stable configuration, and as a result they form positively charged ions called cations.
- <u>Non-metals on the other hand gain electrons to attain stable configuration, and as a result form negatively charged ions called anions.</u>
- <u>Among the elements given above nitrogen (N) gains electrons to form a negatively charged ion called anion. </u>
The two oxygen atoms share two pairs of electrons, so two covalent bonds hold the oxygen molecule together
