Can a particle be a molecule?

Atom is a the smallest particle of a chemical element that can exist.

Molecules is a a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

Particles is a minute portion of matter.

A particle can be a single atom or a molecule ( a group of atoms held together by chemical bonds).

Atoms: a unit of the chemical element

Molecules: a group of atoms bonded together

Particles: tiny bits of matter

Yes, a particle can be a single atom.

Yes, because there's no restriction on how big or small in size particles are.

Explanation:

Atoms are in your body and even in the air you breath and molecules are with the atoms.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
