Answer:
A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together.
The type of bonds holding elements together in a compound can vary: two common types are covalent bonds and ionic bonds.
The elements in any compound are always present in fixed ratios.
Compounds can be decomposed chemically into their constituent elements.
Further differences between compounds and mixtures are listed in the definition of mixture.
