Moseley's Law (1913) - An empirical law concerning the characteristic x-rays that are emitted by the atoms. - This law established the atomic number, that is used to organize and categorize the elements in the periodic table. Experimenting with the energy of beta particles in 1912, Moseley showed that high potentials were attainable from a radioactive source of radium, thereby inventing the first atomic battery, though he was unable to produce the 1MeV necessary to stop the particles.
