An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.

Students use inquiry to identify the elements in Colorflame candles. Unlike traditional flame emission labs, where student see a bright burst of color, this procedure allows students to safely observe an emission spectra and use online tools to match the element.

The unique color that is observed during a flame test is actually a mixture of several different wavelengths of visible light. Chemists can use a spectroscope to identify these various wavelengths. The spectroscope splits light to form an emission line spectrum.

The wavelengths of light given off correspond to the energies involved when electrons move from one energy level to another. These electron movements or transitions show as lines in an emission spectrum for the element. The flame test is a qualitative tool to help determine the identity of a metal ion in a compound.

A flame test is a qualitative analysis used by the chemist to identify the metal and metalloid ion in the sample. Not all metal ions emit colour when heated in the gas burner. A flame test is the simplest way of identifying the presence of group 1 metal ions in the compound.

The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule transitioning from a high energy state to a lower energy state.
