PRACTICE / Nuclear size
Size grows more slowly than nucleon count
In the model R = r₀A^(1/3), compare nuclei with mass numbers 216 and 27.
Find R216/R27.
Organize the givens & assumptions
- A₁ = 216
- A₂ = 27
- same r₀
Spherical nuclear-size model R = r₀A^(1/3), with the same r₀ for both nuclei; ignore shell and surface corrections.
- A
- B
- C
- D
