jul 4, 1914 - Moseley
Description:
He was a British physicist and he used self-built to prove that every element's identity is uniquely determined by the number of protons it has. His discovery enabled him to predict confidently the existence of four new chemical elements, all of which were found. In 1910 Moseley moved to the University of Manchester to join the Ernest Rutherford's research group.Added to timeline:
