WebOzone. In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O 2 ), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. WebDutch chemist Martinus van Marum (1750-1837) discovered ozone around the year 1785, while conducting experiments with electricity. As many high school science students now do, van Marum smelled a distinctive odor while working with oxygen and electricity.
