Question: Which of the following transitions in a hydrogen atom would emit the highest energy photon?

Options:

Correct Answer: n=2 to n=1

Solution:

The transition from n=2 to n=1 emits the highest energy photon as it involves the largest energy difference.

Which of the following transitions in a hydrogen atom would emit the highest energy photon?

Which of the following transitions in a hydrogen atom would emit the highest energy photon?

Step 1: Understand that a hydrogen atom has energy levels, which are represented by 'n' values (n=1, n=2, n=3, etc.).
Step 2: Know that when an electron in a hydrogen atom moves from a higher energy level (n=2) to a lower energy level (n=1), it releases energy in the form of a photon.
Step 3: Recognize that the energy of the emitted photon depends on the difference between the two energy levels.
Step 4: Identify that the transition from n=2 to n=1 has the largest energy difference compared to other transitions (like n=3 to n=2 or n=3 to n=1).
Step 5: Conclude that the transition from n=2 to n=1 emits the highest energy photon.
