Even today, Thompson's model of the atom continues to be called the " plum pudding model."

According to the plum pudding model, the alpha particles should’ve just passed straight through the foil, because atoms would be mostly empty space with some charges scattered around.
The plum pudding model is one of several scientific models of the atom. First proposed by J. J. Thomson in 1904 soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model represented an attempt to consolidate the known properties of atoms at the time: 1) electrons are negatively-charged particles and 2) atoms are neutrally-charged.
