Is not a subatomic particle

A subatomic particle is a particle smaller than an atom, which includes protons, neutrons, and electrons. An example of something that is not a subatomic particle would be a molecule, such as water (H₂O), which is made up of atoms bonded together. Other examples include macroscopic objects, like a chair or a car, which are composed of countless atoms and subatomic particles but are not classified as subatomic themselves.
