WebThis article examines similarities between radical and radical ion reactions. Radicals and radical ions have worked there way into almost every facet of mainstream chemistry over the past 60 years. The importance as well as usefulness now associated with the reactions of radicals is in stark contrast to their prior role as poorly understood scapegoat … 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 example of a radical is the hydroxyl radical (HO·), a molecule that ha…

What is the main difference between an ion and a radical?

WebIon: “Ion is an atom or a group of atoms carrying a positive or negative charge due to loss or gain of electrons.” e.g. cation Na + and Cl 1-is the anion.
