The ozone is diamagnetic, because all of its electrons are paired. O2, by comparison, is paramagnetic, containing two electrons that are unpaired. Ozone, O3, is an unstable and poisonous pale-blue gas. It is a strong allotropic oxygen element; heat is absorbed by a high concentration of ozone around the earth. The molecule containing three atoms of oxygen is ozone. It is unstable at ground level and dangerous.
Ozone is a molecule composed of three atoms of oxygen, also referred to as O3. When heat and sunlight cause chemical reactions between nitrogen oxides (NOX) and volatile organic compounds (VOC), which are also known as hydrocarbons, ozone is produced.
