A) increases
B) decreases
C) remains constant
D) decreases for lower values of n and increases for higher values of n
Correct Answer: B
Solution :
The energy differences between adjacent energy levels in an atom is given by the following relation \[\Delta E=\frac{{{R}_{H}}{{Z}^{2}}}{hc}\left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right]\] or \[\Delta E\propto \left[ \frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}} \right]\] ie, energy difference between adjacent energy levels is inversely proportional to the principal quantum number, n. Therefore, with increase in n, the energy difference will decrease.
