Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the Maltese-cross-shaped target is projected against the tube face at right by a beam of electrons. Electrons are subatomic particles that cause a negative charge in an atom for balance of positive chage and negative charge. Electrons "swirl" around the shell of the atom , which is like a ring.
