A compound is a substance that is made up of two or more elements having chemical bond between each other in a permanent percentage by mass. A molecule is the smallest part of a compound. One or more atoms that are chemically unite to form a molecule.
A molecule is a combination of one of more atoms of a similar type. O2 (oxygen) is a molecule but not a compound. If two atoms of different elements combine it is both a molecule and a compound. H2O (water) is a compound as it contains both hydrogen and oxygen. All compounds (a mixture of elements) are molecules but not all molecules (of the same elements) are compounds.
