Question

which of the following is not an example of a covalent bond?
answer:
a n - n
b mg - n
c n - o
d h - h

Explanation:

Covalent bonds form between non - metals by sharing electrons. Magnesium (Mg) is a metal, and nitrogen (N) is a non - metal. The bond between a metal and a non - metal is typically an ionic bond (formed by the transfer of electrons from the metal to the non - metal). The bonds \(N - N\), \(N - O\), and \(H - H\) are between non - metals (\(N\), \(O\), \(H\) are non - metals), so they are covalent bonds.

Answer:

B. \(Mg - N\)
