J. J. Thomson’s plum pudding model accounted for the presence of negatively charged particles in the atom, which we call “electrons.” Geiger, Marsden, and Ernest Rutherford demonstrated the existence of the nucleus, a dense, positively charged part of the atom in the very center of it.

Hace 5 días · JJ Thomson proposed the Plum Pudding Model shortly after he observed the presence of negatively charged particles that he named electrons. So, if there was a negative charge and the atom was electrically neutral, there had to be a positive charge.

Hace 1 día · At the beginning of the 20th century, J.J. Thomson founded the plum pudding model. This model displayed the atom as a large positively charged ball with small negatively charged electrons embedded inside of it. After the plum pudding model’s discovery, scientists found three types of radiation emanating from atoms, alpha, beta and gamma radiation.
