What did rutherford’s model of the atom include that thomson’s model did not have?

The correct answer is Nucleus.

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.

atomic = no of protons.

mass number-atomic number = neutron number
