Consider a hydrogen like atom whose energy in 
excited state is given by 
when this excited atom makes a transition from excited state to ground state, most energetic photons have energy 
52.224 eV and least energetic photons have energy 
. The atomic number of atom is
Text Solution
Verified by ExpertsThe correct answer is:
A
Maximum energy is liberated for transition 
and minimum energy for 
Hence 
and 
Solving equations (i) and (ii) we get
and 
Now 
. Hence
