The radius of an atom ra_tom can be defined as that value for which 90% of the electron charge is contained within a sphere of radius r_atom. Use the formula in P20.12b to calculate the radius of the H atom.

Reference P20.12b

b. Using this result, show that the probability of finding the electron within a sphere of radius r for the hydrogen atom in its ground state is
