A particular hydrogen like atom has its ground state binding energy 122.4 eV. It is in ground state. Select incorrect option.
Text Solution
Verified by ExpertsThe correct answer is:
B
In ground state, 
Excitation energy from 
to 
Also, when an 
of 125 eV collides with this atom, 122.4 eV energy is absorbed by the atom for ionization of 
and the remaining 2.6 eV will get converted to kinetic energy of the ejected electron.
