Learn how to write and use chemical formulae to represent the chemical proportions of atoms in compounds or molecules. Find out the differences between empirical, molecular, and condensed formulae, and how they relate to chemical names and structures. Chemical formulae provide a way to represent any chemical substance using the symbol of the elements present in it. Provided below is a list of the chemical formulas of some common chemical compounds (along with their molecular weights). Enhance your chemistry knowledge with our comprehensive guide to Chemistry Formulas and Chemical equations with extramarks study material Chemical formula is a way to describe chemical ratios of atoms that make up a specific chemical compound or molecule in chemistry. Chemical element symbols, numbers, and sometimes other symbols, such as parentheses, dashes, brackets, commas, plus (+), and minus (-) signs, are used to represent the chemical elements, atoms, or ions.
