How does the separation between the energy states vary on increasing the principle quantum number (n) in a hydrogen atom?
Answer & explanation
Correct answer: option 1
The energy of the hydrogen atom is given by
En = -13.6/n2
E2-E1 = 10.2 eV
E3-E2 = 1.89 eV
E4-E3 = 0.66 eV
So the enegy level diagram can shown as
So, the energy difference between the states decreases with increasing n.
