In a hydrogen like sample, electron is in 2nd excied state. The Binding energy of 4th state of this sample is `13.6eV`, then

In a H- like sample electron makes transition from 4th excited state of 2nd state then:

A particular hydrogen like atom has its ground state Binding energy = 122 eV . It is in ground state. Then

An electron , in a hydrogen-like atom, is in excited state. It has a total energy of -3.4 eV. Calculate (a) the kinetic energy and (b) the de Broglie wavelength of the electron.

If the binding energy of 2^(nd) excited state of a hydrogen like sample os 24 eV approximately, then the ionisation energy of the sample is approximately

Calculate the energy required to excite an electron in hydrogen atom from the ground state to the next higher state, if the ionsation energy for the hydrogen atom is 13.6 eV .

In hydrogen atom, an electron in its ground state absorbs two times of the energy as if requires escaping (13.6 eV) from the atom. The wavelength of the emitted electron will be

1^(st) excitation Potential of a hydrogen like sample is 15 volt. If all the atoms of the sample are in 2^(nd) excited state then find the K.E. in eV of the electron ejected if a photon of energy (65)/(9)eV is supplied to this sample.

The electron in hydrogen atom in a sample is in n^(th) excited state, then the number of differrent spectrum lines obtained in its emission spectrum will be
