electrons are negatively charged particles
Since table salt is an ionic compound, the formula implies that numbers of Na+<span> ions, and Cl</span>-<span> ions are the same in the solid. The subscript numbers in an empirical formula should have no common divisor. A </span>structural<span> formula reflects the bonding of atoms in a molecule or ion.

Total mass of the crystal:
23 x 2 + 32 + 16 x 4 + 10 x 18
= 322
Mass of water:
10 x 18
= 180
Percentage of water = 180 / 322 x 100 = 55.9%
