When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of. A chemical formula is used a quick way to show the composition of compounds. Letters, numbers, and symbols are used to represent elements and the number of elements in each compound. The empirical formula can be determined from the percentage composition in a subsequent step • Represent chemical reactions Reactants →Products • Skeletal equations – show identities of reactants and products H2 + O2 →H2O • Law of conservation of mass – Atoms are neither created nor destroyed (they only change bonding partners)
