Chemical Formulas are a way of representing the chemical elements and the proportions of the atoms in the compounds with the use of symbols, numbers, paranthesis, dashes, (+), (-) etc., For example, Aluminium Sulphate can be represented as Al2(SO4)3. In other words, the elemental composition of a compound is the chemical formula. It is not the name of the compound and hence not expressed in words. Here, we have listed the chemical formulas of most of the chemical compounds. You can click on the chemical compound to know its molecular weight, density etc.,
A chemical formula used to represent the homologous series of elements is called as the general formula. Hill system is a system used to represent the chemical formula of a compound in an order of carbon atoms at first, hydrogen the second, and then the remaining elements in alphabetical order.
