How does rutherford’s model of the atom compare with thomson’s model? a.) they both describe atoms as small, indivisible spheres. b.) they both describe electrons as moving around the nucleus. c.) they both describe electrons as being surrounded by the positive matter. d.) they both describe atoms as being made up of positive and negative matter.

In Rutherford model and Thomson model there is a small difference as they both are very close models

In Thomson model he proposed that atom is a positively charged sphere in which electrons are randomly distributed all over

While in Rutherford model he proposed that atom has a small volume in which its positive charge is concentrated and all its negative charge in terms of electron revolve around it.

so here we can compare them in following terms

A.) They both describe atoms as small, indivisible spheres.

D.) They both describe atoms as being made up of positive and negative matter.

The correct answer is Option D.

Explanation:

Rutherford gave an experiment known as Gold foil experiment.

In his experiment, he took a gold foil and bombarded it with alpha particles which carries a charge of +2 units. He thought that many of the particles will bounce back from their path. But to his surprise, some of them deflected their path and a few of them bounced back straight from their path.

From these observations, he concluded that in an atom, small positive charge exists which lies in the center. Its because of this positive charge, the alpha particles deflected their path.

J.J. Thomson gave a model known as Plum pudding model. In his model, he states that the electrons are embedded in the pool of positive charge just like plums are embedded in the pudding.

Hence, both the scientists described the positive and negative matter in an atom.

Therefore, the correct answer is option D.
