Bell Ringer Question. Flame Test . Flame Test. According to Bohr theory of the atom, electrons may occupy only specific energy levels. Electrons in atoms jump from their ground state to excited states by absorbing energy. Eventually these electrons fall back to their ground state, reemitting the absorbed energy in the form of light. Because each atom has a unique structure and arrangement of electrons, each atom emits a unique spectrum of light. This characteristic light is the basis for the chemical test known as a flame test. In this test, being placed within a flame excites the atoms. As they reemit the absorbed energy in the form of light, the color of the flame changes. For most metals, these changes are easily visible. However, even the presence of a tiny speck of another substance can interfere with the identification of the true color of a particular type of atom. . UL 94V. The .
