The radius of `n^(th)` orbit of a single electron species is `0.132n^2A^@`. Identify the element.

The difference between the radii of n^(th) and (n + 1)^(th) orbits of hydrogen atoms is equal to the radius of (n-1)^(th) orbit of hydrogen. The angular momentum of the electron in the n^(th) orbit is ___ (h is Planck's constant)

If r_n is the radius of n^(th) orbit of hydrogen atom , then the relative change in the radius, when an electron jumps from n^(th) orbit to (n-1)^(th) orbit is (ngtgt1)

If r_n is the radius of n^(th) orbit of hydrogen atom , then the relative change in the radius, when an electron jumps from n^(th) orbit to (n-1)^(th) orbit is (ngtgt1)

What would be the change in radius of n^"th" orbit, if the mass of electron reduces to half of its original value ?

What would be the charge in radius of n^"th" orbit, if the mass of electron reduces to half of its original value ?
