The ratio of volume of an atom to that of its nucleus is__________________?
Correct answer: A. 1012
- A. 1012
- B. 10-12
- C. 10-8
- D. 108
Explanation
An atom has a characteristic radius near 10⁻¹⁰ m, whereas its nucleus is near 10⁻¹⁴ m; cubing the radius ratio gives an atomic-to-nuclear volume ratio of about 10¹². Thus the nucleus occupies only a tiny fraction of the atom's volume.
