Question

Which of the following transition of an electron in H-atom will emit maximum energy?

• A. $n_6 \to n_5$
• B. $n_1 \to n_2$
• C. $n_3 \to n_2$
• D. $n_4 \to n_3$

Hint:

The energy difference between two levels is greatest when the electron falls from higher levels to lower levels, particularly from $n_3 \to n_2$.

Answer 1

The Correct Option is C

The energy emitted when an electron transitions between two energy levels is proportional to the difference in energy levels.
The larger the difference in energy between the two levels, the greater the energy emitted.
The transition $n_3 \to n_2$ involves a large energy difference compared to the others, resulting in the maximum energy emission.

Thus, the correct answer is (c).
