The subscript in a chemical formula represents the amount of that atom in that compound's formula.
A molecule of Oxygen is composed of two atoms of Oxygen and has the chemical formula O2. There is also another form, known as Ozone, which contains three atoms of Oxygen and has the chemical formula O3.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
Since its chemical formula is C8H18, it contains 8 carbon atoms and 18 hydrogen atoms.
"ch4" is not a proper chemical formula, because the atomic symbol for each element must begin (and may end) with a CAPITAL letter. The chemical formula CH4 contains 5 atoms, one of carbon and four of hydrogen.
The chemical formula is H2O.
