How do the energy gaps between successive electron energy levels in an atom vary from low to high n values?

Options

A. All energy gaps are the same
B. The energy gap decreases as n increases
C. The energy gap increases as n increases
D. The energy gap changes unpredictably as n increases

Answer

B

Explanation

As value of n increases, energy gap decreases due to increasing `Z_(eff)` on valence shell.
