    Democritus discovers atom

    Everything is made of atoms, An infinite number of these atoms exist, These atoms are in motion for all eternity, and empty space is what lies between these atoms.

    Discovers all matter is made up of atoms

    that states all matter is made up of atoms, atoms of the same element are the same, atoms of different elements are different, and atoms combine to form substances. He proposed a model of an atom, similar to a marble.

    The atom is mostly space, with nearly all its mass concentrated in a tiny central nucleus. The nucleus is positively charged and surrounded at a great distance by the negatively charged electrons.
