Table salt is also known as sodium chloride, because it is
made of sodium (Na) and chlorine (CI) atoms. Sodium
chloride is represented by the chemical formula NaCl. This
formula shows that it is made up of sodium and chlorine
atoms. It can also be represented by a ball-and-stick
model, such as the one shown here.
