B Electrons are embedded in a uniform positive sphere.
C The atom contains a small, dense, positively charged nucleus.
Correct Answer
D Atoms of different elements have different masses.
Correct Answer

Option C is the correct answer.

The large-angle deflections indicated that the positive charge and most of the mass of the atom were concentrated in a tiny region called the nucleus, which repelled the positively charged alpha particles.

Hint

What could cause a positively charged particle to be repelled so strongly?
