Examples/Applications For example, in the ionic compound sodium chloride (NaCl), one formula unit consists of one sodium ion (Na+) and one chloride ion (Cl-). In calcium chloride (CaCl2), one formula unit includes one calcium ion (Ca2+) and two chloride ions (Cl-). Chemical Structures/...

For example, sodium chloride, more commonly known as table salt, can be expressed by the formula unit NaCl. Regardless of how many ions of sodium chloride are being used in a chemical equation, the formula unit for sodium chloride is the simplified expression of one sodium atom to one chlori...

are grouped together into a unit, since each sodium ion is equally associated with all its neighboring chloride ions and each chloride ion is equally associated with all its neighboring sodium ions. The formula NaCl, therefore, cannot be taken as showing the composition of some particular unit, ...
The chemical symbols for sodium and chlorine are Na and Cl, respectively, so the formula unit is written as NaCl. Many ionic compounds are slightly more complex, for example, aluminum oxide. Here, oxygen is looking for two electrons, and aluminum wants to give three. They can therefore form...
