In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes. A notable … See more Radicals are either (1) formed from spin-paired molecules or (2) from other radicals. Radicals are formed from spin-paired molecules through homolysis of weak bonds or electron transfer, also known as … See more A large variety of inorganic radicals are stable and in fact isolable. Examples include most first-row transition metal complexes. With regard to main … See more Combustion A familiar radical reaction is combustion. The oxygen molecule is a stable diradical, best represented by O–O . Because spins of the electrons are parallel, this molecule is stable. While the ground state of oxygen is this unreactive … See more In chemical equations, radicals are frequently denoted by a dot placed immediately to the right of the atomic symbol or molecular formula as follows: See more Stability of organic radicals Although organic radicals are generally stable intrinsically (in isolation), practically speaking their existence is only transient because they tend to dimerize. Some are quite long-lived. Generally organic radicals are stabilized by … See more Diradicals are molecules containing two radical centers. Dioxygen (O2) is an important example of a stable diradical. Singlet oxygen, the lowest-energy non-radical state of … See more Until late in the 20th century the word "radical" was used in chemistry to indicate any connected group of atoms, such as a methyl group See more Web1 day ago · 2.

They work by generously giving electrons to free radicals without turning into electron-scavenging substances themselves. They are also involved in mechanisms that repair DNA and maintain the health of cells.
