Molecule
A
molecule
( from
Latin
moles "mass") is an
electrically
neutral group of two or more
atoms
held together by
chemical bonds
. Molecules are distinguished from
ions
by their lack of electrical charge. However, in
quantum physics
,
organic chemistry
, and
biochemistry
, the term
molecule
is often used less strictly, also being applied to
polyatomic ions
.
