Document Summary
The positively charged center of an atom. Almost makes up the entire mass of the atom, but only a fraction of its volume. Proven by rutherford with his gold foil experiment. Shot a beam of positively charged particles through a thin sheet of gold foil. Particles undeflected passed through the empty spaces while those deflected were repelled by a dense positively charged core. Negatively charged particle in the outer part of the atom. Name comes from the greek word for amber . Amber rubbed by cloth creates an electric charge. Used cathode ray (a sealed tube with gas and electrodes and rays to measure deflection of beams) to calculate mass-to-charge ratio of the cathode-ray particle. Ben franklin proved that electricity can travel through gas. Milikan calculated the numerical value of a single unity of electric charge. Mass of 1 electron = 1/2000 the mass of a hydrogen atom. Electrons occupy fixed energy spots at different distances from the nucleus.
