Chemistry

In this lesson, we will learn how to interpret atomic emission spectra to identify elements and determine the compositions of unknown materials.

Worksheet

Q1:

An emission spectrum is produced by passing the light from a blue argon lamp through a prism. In which region of the spectrum are the most intense spectral lines likely to occur?

Q2:

Lithium salts appear red in a flame test. In which region of the spectrum are the most intense spectral lines likely to occur?

Q3:

Molybdenum oxide appears green in a flame test. In which region of the spectrum are the most intense spectral lines likely to occur?
