Patterns of emission or absorption lines in spectra can uniquely identify individual atomic elements, just as dna testing uniquely identifies individual human beings. explain how this is true.

Each atom can uniquely be identified by the type of wavelength of light it emits or absorbs. The light spectrum depends on the jump of an electron from orbital level to another. When an electron absorbs a specific photon of energy, it jumps to a higher orbital level. When it jumps to a lower orbital level, it emits a corresponding light photon. Therefore, using a spectrometer, one can identify types of atoms present in a substance.

Patterns of emission or absorption lines in spectra can uniquely identify individual atomic elements, just as DNA testing uniquely identifies individual human beings is true.

Explanation:

Each part has its own distinctive atomic spectrum. You'll be able to check out the spectra and determine which components are present.

The electrons jumps into increasing energy level when an atom absorbs the energy. Then they jump backtrack once more. Every jump correlate with a specific light wavelength.

There are several potential electron transitions for every atom. Every transition features a specific energy distinction. These types of transitions produce an emission spectrum.  

These emission spectra are as characteristic to every part like fingerprints are to individuals. Thus, it would help scientists to spot the individual atomic elements in them by using the emission spectra.
