The ratio of the nuclear radii of elements with mass numbers 216 and 125 is
Options
- A216: 125
- B216 : 125
- C6: 5
- DNone of these
Correct answer
C. 6: 5
Step-by-step solution
Nuclear radius is proportional to A ^ 1 / 3 , where is the mass number of nucleus. aligned R &= R ₀ ~A ^ 1 / 3 R ₀ &=1.2 fm R ₁ R ₂ &= R ₀(216)^ 1 / 3 R ₀(125)^ 1 / 3 = 6 5 aligned
