| free radical |
an atom or group of atoms with at least one unpaired electron; in the body it is usually an oxygen molecule than has lost an electron and will stabilize itself by stealing an electron from a nearby molecule; "in the body free radicals are high-energy particles that ricochet wildly and damage cells"

| free radical |
A highly reactive chemical that often contains oxygen and is produced when molecules are split to give products that have unpaired electrons (a process called oxidation). Free radicals can damage important cellular molecules such as DNA or lipids or other parts of the cell.

| free radical |
A chemical species that possesses an unpaired electron. These compounds, such as chlorine monoxide (ClO), hydroxyl radical (OH), and nitric oxide (NO), are characterized by a high chemical reactivity. Free radicals are often generated in the atmosphere from the photodissociation of more stable species. Their subsequent chemistry is central to such environmental issues as stratospheric ozone depletion and tropospheric oxidant production.
