Atomic Spectra Answers

The emission spectrum of the element lithium is shown below.What is the best estimate of the color that will be seen when a sample of lithium gas absorbs a lot of energy?

A green dot in the middle of 4 concentric circles. The first away from the green dot is labeled n = 1. The second circle away from the green dot is labeled n = 2. The third circle away from the green dot is labeled n = 3 and the last is labeled n = 4. There is an arrow from n = 4 to n = 1 labeled A. There is an arrow from n = 3 to n = 2 labeled B. There is an arrow from n = 3 to n = 1 labeled C. There is an arrow from n = 2 to n = 1 labeled D.

What are characteristics of absorption spectra? Select 3 options. Light is absorbed, which produces characteristic lines.Light is emitted, which produces characteristic lines.Lines are dark on a visible light background.Lines are brightly colored on a black background.Lines are produced by electrons being excited.Lines are produced from electrons returning to a lower energy level.

What is released when an excited electron returns to a lower energy state?
