What did JJ Thompson's model of the atom look like? What was the name of this model?

a) Thompson's model depicted a solid, uniform sphere. It was called the "Plum Pudding Model."
b) Thompson's model showed electrons orbiting a central nucleus. It was called the "Planetary Model."
c) Thompson's model had a dense, positively charged nucleus at the center. It was called the "Solar System Model."
d) Thompson's model portrayed electrons as waves. It was called the "Wave-Particle Duality Model."

Final answer:

J.J. Thomson's model of the atom was called the "plum pudding" model. The electrons were embedded in a uniform sphere of positive charge, and the positive matter was jelly-like or similar to a thick soup. The electrons were somewhat mobile and were pulled back toward the center region of the atom.

Step-by-step explanation:

J.J. Thomson's model of the atom was called the "plum pudding" model. In this model, the electrons were embedded in a uniform sphere of positive charge, like blueberries stuck into a muffin. The positive matter was thought to be jelly-like or similar to a thick soup, and the electrons were considered somewhat mobile. As they got closer to the outer portion of the atom, the positive charge in the region was greater than the neighboring negative charges, and the electron would be pulled back toward the center region of the atom.
