In a single isolated atom an electron make transition from 5th excited state to 2nd state then maximum number of different types of photons observed is

In a H-like sample, electrons make transition from 4^(th) excited state upto 2^(nd) state. Then ,

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

In a single isolated atom of hydrogen electron make transition from 4^(th) excited state to grond state producing maximum possible number of wavelengths if the 2^(nd) lowest energy of these lines is used to further excite an already excited sample of Li^(2+) ion then transition will be

As an electron makes a transition from an excited state to the ground state of hydrogen-like atom // ion:

If electron make transition from 7^(th) excited state to 2^(nd) state in H atom sample find the max. number of spectral lines observed.

If electron make transition from 7^(th) excited state to 2^(nd) state in H atom sample find the max. number of spectral lines observed.

As an electron makes a transition from an excited state to the ground state of a hydrogen like atom/ion.
