H-atom from first orbit to second orbit is :-
of its ionisation energy
(2)
of its ionisation energy
(3) – of its ionisation energy
(4) None
The ionisation potential of a singly ionised heli
n
)​

Answer 1

Answer:

For example an electron in the ground state has an energy of -13.6 eV. The second energy level is -3.4 eV. Thus it would take E2 − E1 = -3.4 eV − -13.6 eV = 10.2 eV to excite the electron from the ground state to the first excited state.
