atom

Democritus believed that light refracting through atoms caused the phenomenon that we perceive and describe conventionally, or by mutual agreement, as color.

Their components function like atoms in conventional materials but have special optical, electrical and magnetic properties.

These are solids formed from large molecules with a significant number of atoms, often including elements like carbon, nitrogen or oxygen, arranged in a ring.

Finally elementary particles are protons, electrons, neutrons and all other particles that are smaller than an atom.

The structures are held together by some of the strongest chemical bonds in nature, including the ones that turn carbon atoms into diamonds.
