In an inelastic collision an electron excites a hydrogen atom from its ground state to a 
-shell state. A second electron collides instantaneously with the excited hydrogen atom in the 
-shell state and ionizes it. At least how much energy the second electron transfers to the atom in the 
-shell state?
Text Solution
Verified by ExpertsThe correct answer is:
D
The ground state of hydrogen ( 
) is represented by 
, the first excited state 
is represented by 
, the second excited state 
is represent by 
. So, the energy transferred by the second electron can be given by
