Ozone is an allotrope of, for 10 points, what element with atomic number 8, the second-most abundant in Earth's atmosphere?
A technique for inserting this element adjacent to carbonyl was developed by Baeyer and Villiger, and it is half as prevalent as carbon in a family of compounds used for phase transfer catalysis called crown ethers. This element's triplet ground state makes it highly (*) paramagnetic, and it is found along with aluminum and hydrogen in the ore bauxite. A compound consisting of three atoms of this element absorbs harmful UV rays in the upper atmosphere, and it reacts under heat with hydrocarbons in combustion.
