Why is it not correct/precise to say "a molecule of salt?"
Fynjy0 [20]

It is not correct to say " a molecule of salt " because salt is a compound.

Explanation:

  • As we know a molecular bond is present in each molecule.
  • Salt (NaCl) is considered as a compound because it is made up of two types of elements that are sodium as well as chlorine.
  • On the other hand it is not considered as a molecule as it is not holding an ionic bond.
  • As a result we can name it as an ionic compound. Hence it is not considered as a molecule of salt.
