The radius of Bohr first excited state is a• . The electron in n th orbit has a radius

Answers (1)

Radius of nth orbital -

r_{n}= \frac{\epsilon _{0}n^{2}h^{2}}{\pi mZe^{2}}

 

- wherein

r_{n}\alpha \: \frac{n^{2}}{Z}

\frac{\epsilon_{0}h^{2}}{\pi me^{2}}= 0.529A^{\circ}

 

 r=\frac{n^{2}}{z} a_{0}

For z=1, r=n^{2}a_{0}
