SUMMARY
The order of atoms in chemical formulas is determined by established conventions set forth by the International Union of Pure and Applied Chemistry (IUPAC), specifically outlined in the IUPAC Red Book. For instance, in the formula CO2, carbon is listed before oxygen due to its higher electronegativity and the standard practice of placing the more electropositive element first. This systematic approach ensures clarity and consistency in chemical nomenclature, which is crucial for effective communication in the scientific community.
