Sodium chloride, commonly known as table salt, is a compound with the chemical formula NaCl. It is an essential mineral for human health and is widely used in food preparation and preservation.
Sodium chloride is formed through the combination of sodium (Na) and chlorine (Cl) atoms through an ionic bond. Sodium loses an electron to chlorine, resulting in the formation of Na+ and Cl- ions, which are held together by electrostatic forces to form the compound NaCl.
