An absorption spectrum occurs when a photon is absorbed, exciting an electron to a higher quantum energy state. Absorption spectra involve atoms increasing in energy level. An emission spectrum occurs when a photon is emitted as an electron drops to a lower quantum energy state, with emission spectra involving electrons decreasing their energy level. The document also provides a conversion between electronvolts (eV) and joules (J).

- 2. Absorption Spectrum Absorption spectra always involve atoms going up in energy level. 0 eV -10 eV ionized
- 3. Emission Spectrum Photon is emitted and electron drops to lower quantum energy state. 0 eV -10 eV hf Excited state DE
- 4. Emission Spectrum Emission spectra always involve electrons going down in energy level. 0 eV -10 eV ionized
- 5. Converting eV to Joules (J) 1 eV = 1.602 x 10-19J
