Question

Which of the following electronic transitions in a hydrogen atom will require the largest amount of energy?

• A. n = 1 to n = 2
• B. n = 2 to n = 3
• C. n = 1 to n = $\infty$
• D. n = 3 to n = 5

Answer 1

The correct option is C n = 1 to n = $\infty$

As the energy level increases, the energy gap decreases progressively. So, the maximum energy for an electronic transition is required when the electron jumps fron n = 1 to n = $\infty$.
