Answer :
we know that
The radius of the hydrogen atom is [tex]0.529*10^{-10}m[/tex]
The radius of the nucleus is [tex]1.2*10^{-15}[/tex]m
the ratio is equal to
[tex]\frac{0.529*10^{-10}}{ 1.2*10^{-15}} = 44,083.33[/tex]
that means the radius of the hydrogen atom is 44,083.33 times the radius of the nucleus
therefore
the answer is
the ratio is equal to 44,083.33
