Web9 nov. 2024 · In chemistry, the nucleus is the central core of an atom. It’s the part that contains most of the atom’s mass. In cell biology, nucleus usually refers to a structure inside a cell that contains the cell’s genetic information. 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…
