James Chadwick was born in England on October 20th, 1891. He attended Manchester University and received his degree from the Honors School of Physics. Chadwick’s big influence on chemistry was when he accomplished the transmutation of light elements. He did this by bombarding them with alpha particles. In doing this he could study the structure of the atoms nucleus. Which lead to him proving that neutrons were real. Chadwick’s discoveries lead to the construction atomic bomb.
