Question
What discovery led to the rejection of Dalton’s solid sphere model of the atom?
Correct Answer
Option D is the correct answer.

Dalton's model proposed that atoms were indivisible. The discovery of subatomic particles like the electron, proton, and neutron showed that atoms are, in fact, divisible and have an internal structure, leading to the rejection of the solid sphere model.
Hint
What was found to be inside the atom, proving it was not solid and indivisible?
