Cathode rays are streams of fast-moving neutrons.
Most of the mass of an atom is concentrated in the positively charged nucleus. Select the valid set of electron configurations for these atoms. Rutherford used light scattering experiments to propose that A. energy is radiated when an electron goes from a higher energy level to a lower energy level. B. the atom consists of a very small, positively charged nucleus surrounded by electrons. E. electromagnetic radiation has properties associated with photons.
