Question

Radius of hydrogen nucleus is 0.8 X 10-15 m. Calculate the radius of Be4 8 nucleus.

Answer 1

Find-We have to calculate the Radius of Be nucleus

Explanation:

We know the relation between the Radius is directly proportional to the atomic mass

Given-

Atomic mass of Hydrogen=1

Atomic mass of Be=8

We can find the Radius of the Be nucleus By the formula given below

$\frac{R_{H} }{R_{Be} } =(\frac{A_{H} }{A_{Be} })^{1/3}$

$\frac{0.8\times10^{-15} }{R_{Be} }=\frac{1}{8}\\R_{Be}=8 \times0.8\times10^{-15} =6.4\times10^{-15}$ m

Hence the radius of Be nucleus is $6.4\times10^{-15}$
