The wave function for a 15 -orbital in bydeogen atom is givem by $${?}_{15}(n)=\frac{1}{\sqrt{n}}{\left(\frac{1}{a_0}\right)}^{3/2}{e}^{?\frac{n}{90}}$$ Where $$r$$ is the nadius of the orbital and $$q$$ is a constant called the Bohr radius? $$a_1=5.292\times 10^{?11}$$ Calculate the expectation value of $$r$$ foir an electron in the 15 orbital of a hydrogen atom. Hint: $$dz=n^{2}dr\frac{\sin ?d?d?}{?94{?}^2}$$ $$dz=n^{2}dr4?$$ after angular integration
