Diagram of the emission spectra of iron. with clusters of blue, green, yellow and red lines

If the atoms of a given element have a combination of possible orbital jumps that is different from the combinations possible for the atoms of other elements, then every element will display its own unique emission spectrum. The following diagram shows the emission spectra for various elements. Notice how the emission lines are diagnostic, much like a bar code or a fingerprint.
