Worked Solution & Example Answer:Identify the main energy levels involved in the electron transition that gives rise to the first (red) line of the Balmer series in the emission spectrum of the hydrogen atom. - Leaving Cert Chemistry - Question b - 2017
Step 1
Identify the main energy levels involved
Answer
The first (red) line of the Balmer series corresponds to the electron transition from the energy level n=3 to n=2. This transition occurs when an electron falls from the third energy level (3) to the second energy level (2), resulting in the emission of a photon that is observed as the red line in the hydrogen spectrum.
