This document describes a flame test experiment to identify metals based on the color they produce in a Bunsen flame. The experiment lists various metal compounds and the colors they produce, including lithium (crimson red), sodium (yellow), potassium (lilac), calcium (orange), strontium (red) and barium (green). It explains that the flame heats the metals, moving their electrons to higher energy levels, and as they cool the electrons fall back and emit characteristic colors.
