Explanation:

- Sir JJ Thomson proposed the ‘plum pudding’ model. He suggested that the atom consists of electrons scattered throughout a sphere of positive charge, similar to plums within a pudding. ?? Correct Answer: Sir JJ Thomson

- Robert Andrews Millikan is best known for his oil-drop experiment, which measured the charge of the electron.

- Ernest Rutherford conducted the gold foil experiment, disproving the plum pudding model and proposing the nuclear model of the atom where electrons orbit a dense, positively charged nucleus.

- Henri Becquerel discovered radioactivity but did not propose a model of the atom.
