A molecule is a combination of two or more atoms that are joined together by chemical bonds. Molecules can be simple or complex and can be organic or inorganic compounds.

Size

Atoms are the smallest units of an element, while molecules are much larger than atoms and are made up of a combination of atoms.

Composition:

Atoms are made up of subatomic particles, while molecules are made up of atoms linked together by chemical bonds.

Properties

• Atoms have unique chemical properties that allow them to combine with other atoms to form molecules.
• Molecules have unique properties based on the composition of the atoms that make them up.

State of matter

Atoms can exist in a solid, liquid or gaseous state. Molecules can also exist in these states, but they can also exist in a plasma state or dissolved in a liquid.
