Question

What is the ratio of radii of the orbits corresponding to first excited state and ground state in a hydrogen atom? Zigya

Answer 1

Radius of the nth orbit is given as rn=(n2/m)(h/2π)2 (4πϵ0/e2) For the ground state, n=1 For excited state, n=2 So the ratio between radii of the first orbital & the ground state radii is 4.

I hope it helps
