How do electrons compare in size with protons and neutrons?
AThey are far heavier
BThey are far fewer
CThey are far smaller
DThey are far slower
Answer & Solution
Correct answer: C. They are far smaller
1. Protons and neutrons sit packed together in the nucleus at the centre.
2. Electrons move in a wide zone around that nucleus at very high speed.
3. Electrons are about 2000 times smaller than protons and neutrons.
4. They are also lighter, not heavier, so the option about weight is wrong.
