alleryThe radius of a nucleus is smaller than the radius of an atom by a factor of about:
ATen hundred
BTen billion
CTen million
DTen thousand
Answer & Solution
Correct answer: D. Ten thousand
1. An atom is mostly empty space around a tiny core.
2. The size gap between the two is enormous.
3. The radius of the nucleus is smaller than the radius of an atom by a factor of ten to the fourth.
4. So the factor is about ten thousand.
