Similarly, molecular formulas have to have subscripts after the element name, not before.

类似的，分子式中的下标是在元素符号后边的，而不是前边。

A formula contains the symbols of the kinds of atom in the each molecule and subscripts that indicate the number of each kind of atom in the molecule.

分子式中含有原子符号，下标的数字表示分子中每种原子的数量。
