All compounds are molecules, but not all molecules are compounds. A molecule is just any grouping of atoms. Nonetheless, when the atom combinations differ from elements, its referred to as a compound. Hydrogen gas (H2)as well as oxygen (O2), are all molecules since they contain 2 or more...
1.the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound. 2.a quantity of a substance, the weight of which is numerically equal to the molecular weight; gram molecule. ...
A molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.
Molecule definition: the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.. See examples of MOLECULE used in a sentence.
