Question
Consider a hydrogen like atom whose energy in nth excited state is given by En = -
when this excited atom makes a transition from excited state to ground stat, most energetic photons have energy Emax = 52.2224 eV and least energetic photons have energy Emin = 1.224 eV. The atomic number of atom is -
Options
A.2
B.5
C.4
D.None of these
Solution
Hence
- E1 = 52.224eV and
= 1.224eV ⇒ E1 = - 54.4eV and n = 5
Now E1 = -
= - 54.4 eV. Hence Z - 2
Now E1 = -
