The discovery of atomic structure in the early 1900’s was discussed in chapter 2 of your textbook. one atomic model proposed during this period was the plum pudding model. which statement best describes this model?

(a) most of the atom is "empty space" with an electron moving in a region outside of the nucleus.
(b) all three of the other options are correct
(c) it included negatively charged particles.
(d) it relied on millikan's determination of the electron's charge.

The correct option is: (C) It included negatively charged particles.

Explanation:

Sir Joseph John Thomson proposed an atomic model, known as the plum pudding model in 1904.

In this model, he compared an atom to a plum pudding and suggested that the negatively charged electrons are the plums that are embedded in a uniform positively charged spherical pudding.

Therefore, according to the plum pudding model, an atom has no net electric charge and contains negatively charged electrons.
