The correct term for ionic salts (as sodium chloride) is formula unit, not molecule; sodium chloride form very large structural lattices.
Sodium chloride is encountered as an ionic solid, with a giant ionic lattice structure, containing Na+ and Cl- ions. Sodium chloride in the solid state is not molecularIn sodium chloride vapour at high temperatures there are discrete NaCl diatomic molecules
The bond in the diatomic chlorine molecule Cl2 is a covalent bond where electrons are shared between atoms. In sodium chloride NaCl, the bond is an ionic bond where electrons are transferred from sodium to chlorine, resulting in the formation of positively and negatively charged ions that are attracted to each other.
In the giant ionic lattice each sodium ion is surrounded by 6 chloride ions in and octahedral array. Likewise each chlorine is surrounded by 6 sodium atoms. Molecular NaCl , formed at high temperature in the gas phase is found a diatomic molecules NaCl as well as (NaCl)n . The diatomic molecule has a very high dipole moment indicating that the bonding is principally ionic.
Sodium is not diatomic. Sodium is a metallic element that typically exists as individual atoms in its elemental form. Diatomic molecules, on the other hand, are molecules made up of two atoms of the same element bonded together. An example of a diatomic molecule is diatomic oxygen (O2).
Sodium chloride has two atoms in the formula unit (NaCl): sodium and chlorine.
Sodium chloride is a compound.
Sodium chloride is not a cause of cancer.
Potassium is not a diatomic element. Diatomic elements are those that naturally exist as molecules with two atoms bonded together, such as chlorine (Cl2), iodine (I2), and hydrogen (H2). Potassium (K) does not naturally form diatomic molecules.
Sodium chloride is formed from sodium and chlorine.

Solid sodium chloride is not an electrolyte.Sodium chloride in water solutions or molten sodium chloride are electrolytes.
Sodium and chlorine are the only elements in sodium chloride.
