molecule Definition
mol·ecule (mäl′ə kyo̵̅o̅l′)
noun
- the smallest particle of an element or compound that can exist in the free state and still retain the characteristics of the element or compound: the molecules of elements consist of one atom or two or more similar atoms; those of compounds consist of two or more different atoms
- a small particle
Etymology: Fr molécule < ModL molecula, dim. of L moles, a mass: see mole
