Three forms (or allotropes) of oxygen are involved in the ozone-oxygen cycle: oxygen atoms (O or atomic oxygen), oxygen gas (O 2 or diatomic oxygen), and ozone gas (O 3 or triatomic oxygen). Ozone is formed in the stratosphere when oxygen gas molecules photodissociate after absorbing UVC photons. This converts a single O 2 into two atomic oxygen radicals. The atomic oxygen radi… Web158 Likes, 3 Comments - Alabama School of Math & Sci (@asmsdragons) on Instagram: "Toshiba/NSTA ExploraVision Competition ASMS student teams competed in the Toshiba ...
