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.
