If radius of the A1327lA 1327 l nucleus is taken to be RAl{R}_{Al} then the radius of Te53125Te 53125 nucleus is nearly

Options

  1. A(5313)13RAl\left(\dfrac{53}{13}\right)\dfrac{1}{3}{R}_{Al}
  2. B53RAl\dfrac{5}{3}{R}_{Al}
  3. C35RAl\dfrac{3}{5}{R}_{Al}
  4. D(1353)13RAl\left(\dfrac{13}{53}\right)\dfrac{1}{3}{R}_{Al}

Correct answer

B. 53RAl\dfrac{5}{3}{R}_{Al}

Step-by-step solution

We know, the radius of the nucleus is R=R0(massNumber)13R = {R}_{0}\left(massNumber\right)\dfrac{1}{3}
R=R0A13R = {R}_{0}A\dfrac{1}{3}
RAlRTe=(27725)13=35\dfrac{{R}_{Al}}{{R}_{Te}} = \left(\dfrac{27}{725}\right)\dfrac{1}{3} = \dfrac{3}{5}
RTe=53RAl{R}_{Te} = \dfrac{5}{3}{R}_{Al}
