Does a Spectroscopy Identify Elements?

Spectroscopy is the practice of examining spectra and comparing them to those of known elements. Using spectroscopy methods, scientists can identify pure substances or compounds and the elements in them.

How does spectroscopy work to identify elements?

By looking at the pattern of lines, scientists can figure out the energy levels of the elements in the sample. Since every element has unique energy levels, the spectra can help identify elements in a sample.

How can specific elements be identified?

There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question.
