If the radius of the 1 3 2 7 Al nucleus is estimated to be 3 . 6 Fermi, then the radius of 5 2 1 2 5 Te nucleus be nearly :

Options

  1. A6 Fermi
  2. B8 Fermi
  3. C4 Fermi
  4. D5 Fermi

Correct answer

A. 6 Fermi

Step-by-step solution

R R 0 1 1 / 3 R AI R Te = R 0 A AI 1 / 3 R 0 A Te 1 / 3 = 3 5 ∴ R Te = 5 3 × 3 . 6 R Te = 6 Fermi
