Which of the following would form an anion? He H N B

N because it has a negative charge

Answer;

Nitrogen (N)

Explanation; 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. Non-metals on the other hand gain electrons to attain stable configuration, and as a result form negatively charged ions called anions. Among the elements given above nitrogen (N) gains electrons to form a negatively charged ion called anion.
