If an electron is present in n =6 level . How many maximum spectral lines would be observed in case of H atom-

In Hydrogen atom electron is present in the N shell. If it loses energy, a spectral line many be observed in the region

How many spectral line of balmer series present in visible region :

If in a gaseous sample of one mole of hydorgen atoms, the electron in every H atom is present in the 5th orbit, then how many spectral lines would appear in its emission spectrum?

An electron jumps from fourth to first orbit in an atom. How many maximum number of spectral lines can be emitted by the atom ?

An electron in an excited hydrogen atom acquired an energy of 12.1 eV. To what energy level did it jump? How many spectral lines may be emitted in the course of the transition to lower energy level? Calculate the corresponding wavelengths.

Whwn the electron in an excited hydrogen atom jumps from an energy level for which n=5 to level for which n=2 ,the spectral line is obeserved in which series of the hydrogen spectrum?
