alleryThe density of a nucleus is described as being independent of which quantity?
AThe marking number
BThe mass number
CThe magnet number
DThe mixing number
Answer & Solution
Correct answer: B. The mass number
1. Nuclear radius grows as the cube root of the mass number.
2. Volume therefore grows in proportion to the mass number itself.
3. Thus the density of nucleus is a constant, independent of A, for all nuclei.
4. So it does not depend on the mass number.
