Flame Tests of Metal Cations
Scientists used flame tests to identify elements long before the invention of emission spectroscopy. Young chemists observe a flame test of five metal cations in the fourth lesson of an 11-part series. Individuals then work...

Flame Test
Young scholars conduct a flame test on different substances. In this chemistry lesson, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.
