Question
A particular hydrogen like atom has its ground state ground state binding energy 122.4 eV . is It in ground state. Then
Options
A.Its atomic number is 3
B.An electron of 90 eV can excite it
C.An electron of kinetic energy nearly 91.8 eV can be brought to almost rest by this atom
D.An electron of kinetic energy 2.6 eV may emerge from the atom when electron of kinetic energy 125 eV collides with this atom
Solution
122.4 = 
⇒ z = Z = 3 ; 91.8 = 122.4 
So an electron of KE 91.8eV can transfer its energy ti this atom.
⇒ z = Z = 3 ; 91.8 = 122.4 So an electron of KE 91.8eV can transfer its energy ti this atom.
