Question

which of the following correctly describes why the plum pudding model is no longer accepted as an accurate model of the atom?
there arent actually negatively charged particles in atoms
scientists found new evidence and revised the theory to fit the data better
scientists discovered that atoms actually have positively charged particles dispersed throughout a negative mass
scientists revised the evidence to fit this model of the atom better

Explanation:

The plum - pudding model was replaced because scientific understanding evolves. As new evidence (like the discovery of the nucleus in Rutherford's experiments) is found, theories are revised. The plum - pudding model proposed a uniform distribution of charge, but new evidence showed a different atomic structure.

Answer:

B. Scientists found new evidence and revised the theory to fit the data better.
