Question 617: Atoms & Nuclei

Question

The radius of germanium (Ge) nuclide is measured to be twice the radius of $${}_4^9$$Be. The number of nucleons in Ge are

Accepted Answer

For berillium, R
1
= R
0
(9)
1/3
For germanium, R
2
= R
0
A
1/3
$${{{R_1}} \over {{R_2}}}$$ = $${{{{\left( 9 \right)}^{1/3}}} \over {{A^{1/3}}}}$$
$$ \Rightarrow $$ $${1 \over 2}$$ = $${{{{\left( 9 \right)}^{1/3}}} \over {{A^{1/3}}}}$$
$$ \Rightarrow $$ $${1 \over 8} = {9 \over A}$$
$$ \Rightarrow $$ A = 72
