What is the chemical formula for table salt?

Explanation:
Salt is an ionic compound formed from sodium ions and chloride ions in a 1:1 ratio. Sodium loses one electron to become Na+, and chlorine gains one to become Cl−. When these ions pair, they form NaCl, a neutral compound. The other formulas point to different substances: KCl is potassium chloride, Na2SO4 is sodium sulfate, and CaCl2 is calcium chloride, each with different ions and ratios. So the formula that matches table salt is NaCl.
