Question

the plum pudding model
the indivisible atom model

Explanation:

J. J. Thomson discovered electrons. He proposed the plum - pudding model, where electrons are embedded in a positively charged "soup" like plums in a pudding. The indivisible atom model was proposed before the discovery of sub - atomic particles. The idea of an atom with a lot of empty space and a concentrated nucleus was from Rutherford's gold foil experiment.

the plum pudding model
