dioxides
Compounds with paired oxygens
Dioxides are chemical compounds containing two oxygen atoms bonded to another element.
The most familiar is carbon dioxide, the gas we exhale and that plants absorb, which also traps heat in the atmosphere.
Sulfur dioxide and nitrogen dioxide are industrial pollutants that contribute to acid rain and smog.
Silicon dioxide, better known as silica, is the main component of sand and glass.
