Important Questions from Nuclear Physics
Which of the following is a unit of nuclear radius?
Show answer
Fermi
Fermi (1 fm = 10⁻¹⁵ m) is the unit used to express nuclear radius.
The radius of a nucleus is proportional to:
Show answer
A¹/³
The nuclear radius R is given by R = r₀A¹/³, so it is proportional to the cube root of mass number.
The symbol \( {}_{Z}^{A}X \) represents:
Show answer
A nucleus
The notation \( {}_{Z}^{A}X \) is used to represent a nucleus with atomic number Z and mass number A.
Atoms with the same atomic number but different mass numbers are called:
Show answer
Isotopes
Isotopes are atoms of the same element (same Z) but different mass numbers (different A).
