James Chadwick was an English physicist who discovered the nuetron in 1932. The nuetron was named because it lacked an electrical charge. Chadwicks discovery was crucial because unlike alpha particles nuetrons did not have an electricla charge allowing them to pass through the nuclues of the heaviest elements. Chadwicks discovery made it possible for scientist to develope elements heavier than Uranium in a lab. Chadwick won the Nobel Prize for his work in 1935.
