1A.11

[Aliya Jain 2B]

Question 1A.11 asks: In the spectrum of atomic hydrogen, several lines are generally classified together as belonging to a series. What is common to the lines within a series that makes grouping them together logical? Does anyone know how to approach this question? I'm a little confused on the concept.

Series refers to the Lyman (n=1) , Balmer (n=2), Paschen (n=3), and Brackett (n=4) series. What makes the lines of each series similar is that when electrons relax to a lower energy level they emit an EMR. For electrons relaxing to n=2 for example, they emit an EMR that corresponds to the Balmer series. Figure 2.1 in the textbook can help you out as well :)

A series is all transitions from a certain energy level For example, all transitions from n=1 to n=x energy level is a series and then transitions from n=2 to n=x to energy level is another series
