Sodium Chloride or NaCl is made up of two elements, sodium (or Na) and chlorine (or Cl). A molecule of sodium chloride, NaCl, consists of one atom each of sodium and chlorine. Hence, each molecule of NaCl has 2 atoms total.

Similarly, we can calculate the total number of atoms in 1 mole of sodium chloride. Since 1 molecule contains 1 atom each of Na and Cl, 1 mole of NaCl will contain 1 mole each of Na and Cl. We know that 1 mole of anything contains an Avogadro's number of atoms or 6.023 x 10^23 atoms.

Thus, 1 mole of NaCl will contain 6.023 x 10^23 atoms each of Na and Cl, or a total of 12.046 x 10^23 atoms.

NaCl is an ionic compound formed by the loss of one electron from Na and the gain of the one electron by Cl. It is also known as common salt.

Hope this helps.
