in charge, researchers believed that atoms must also contain positively-charged particles that balanced the negatively-charged electrons. This idea, together with research into radioactivity, led Ernest Rutherford to the discovery of the atomic nucleus in 1911. Rutherford saw the nucleus as the home ...
