Answer 2

An atom of compound would be incorrect to use. (Option D)

• The atoms are not independently present in the chemical compounds.

• A chemical compound is only made out of chemical molecules and the atoms form those molecules.

• So,we can use the phrase,a molecule of chemical compound instead of the an atom of molecule because molecules are the constituents of the chemical compounds not the atoms.

For example - A molecule of sodium chloride is a correct statement and an atom of sodium chloride is a wrong statement.
