WebIn a Van de Graaff generator, invented in 1929 by Robert J. Van de Graaff, an endless rubber or fabric belt carries electric charges from a roller at the base of the device and deposits them inside a hollow metal electrode at the top. This causes a high voltage to develop between electrodes at the top and bottom of the apparatus.

"Though the word atom originally denoted a particle that cannot be cut into smaller particles, in modern scientific usage the atom is composed of various subatomic particles. The constituent particles of an atom are the electron, the proton and the neutron. The electron is by far the least massive of these particles at 9.11×10 kg, with a negative electrical charge and a size that is too small to be measured using available techniques. It was the lightes… " - How are atoms built
