MCQ
The principal quantum number increases, the difference of energy between consecutive energy levels:
  • A
    Decreases.
  • B
    Ncreases.
  • C
    Remain same.
  • D
    Ometimes increases and sometimes decreases.
✓

Answer

  1. Decreases.

Explanation:

Difference in energy is given as; $\triangle\text{E}=\frac{\text{Z}^2\text{R}}{\text{n}^2}$

Therefore, as principal quantum number(n) increases the energy of transition decreases.
