Compounds. A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. 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.
Compounds are pure substances made of atoms of two or more elements chemically combined in fixed ratios. Compounds must meet all of these criteria: Compounds are pure substances and not mixtures. Compounds are pure substances and not mixtures. 2  For example, table salt is not a compound because it is a mixture of sodium chloride, dextrose and calcium silicate (to keep it from clumping in high humidity) and potassium iodide (an important nutrient necessary for proper thyroid function).
