The nucleus was discovered in 1911, as a result of Ernest Rutherford's efforts to test Thomson's "plum pudding model" of the atom. The electron had already been discovered by J.J. Thomson. Knowing that atoms are electrically neutral, J.J.Thomson postulated that there must be a positive charge as well. In his plum pudding model, Thomson suggested that an atom consisted of negative electrons randomly scattered within a sphere of positive charge. Ernest Rutherford late… WebErnest Rutherford discovered the atomic nucleus, the compact, dense region made up of protons and neutrons at the heart of an atom, in 1911 using the Geiger-Marsden gold foil experiment from 1909.
