In the 1990s we thought we’d identified the root cause of aging: nasty molecules called ,free radicals, that wreaked havoc on our cells. Even better, we’d figured out how to counteract them with loads of antioxidants. Then science started raising questions. Learn more about your ad-choices at https://www.iheartpodcastnetwork.com

• Electron-deficient molecules (central Be or B) and odd-electron species (,free radicals,) have less than an octet around the central atom but often attain an octet in reactions. • In a molecule (or ion) with a central atom from Period 3 or higher, the atom can hold more than eight electrons because it is larger and uses d orbitals to expand its valence shell.

Ultraviolet germicidal irradiation - Wikipedia

Ultraviolet germicidal irradiation, (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification.
