Question

What did Rutherford’s model of the atom include that Thomson’s model did not have?

Answer 1

Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.

Answer 2

The correct answer is Nucleus.

Step-by-step explanation:

The main difference between Rutherford's model and Thomson's is the inclusion of the nucleus, which the latter did not have. Another notable difference between these two models is that Thomson thought that the electrons were located within the positive part, but Rutherford shows a model whose satellite-like electrons are separated from the nucleus.
