Question

When salt is dissolved in water it actually breaks down into two different substances is salt composed of atoms or molecules

Answer 1

Something like table salt (NaCl) is a compound because it is made from more than one kind of element (sodium and chlorine), but it is not a molecule because the bond that holds NaCl together is an ionic bond.

Answer 2

Salt is an ionic compound, consisting of a crystal, lattice structure of the two ions Na+ and Cl-. Salt water is full of sodium chloride molecules. ... The chlorine has one extra electron and its outer electron shell is complete, so like sodium it too cannot bond with other atoms.
