Each element has it's own emission spectrum. You could call it a "Fingerprint" that is unique to each element. Can you explain what creates this fingerprint? A. The electrons in an atom tend to be arranged in such a way that the energy of the atom is as low as
possible: this is called the ground state.

B. Atomic emission spectra are produced when excited electrons return to ground state.

C. The atomic emission spectrum is the pattern of lines formed when light passes through a prism to separate
it into the different frequencies of light it contains.

D. Oxygen has more electrons than hydrogen which leads to more possible line spectra.

E. Atomic emission spectra are produced when electrons in the ground state are excited and jump to another
energy level, emitting electromagnetic waves in the process.
