Web27. dec 2015 · Redox reactions, as taught at the general chemistry level, involves changes in formal oxidation state. What's an oxidation state? It's the hypothetical charge that an atom would have if all bonding were ionic (as opposed to covalent, or electron-sharing). WebThe term redox is a combination of the words reduction and oxidation. It refers to all reactions that involve the transport of electrons from an electron donor to an electron acceptor. A molecule that gets reduced gains electrons, and loses electrons when it gets oxidized (see Figure 1). For a redox reaction to occur, a molecule has to be ...

Web23. jan 2024 · Jan 22, 2024. In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has unpaired valence electrons or an open electron shell, and therefore may be seen as having one or more "dangling" covalent bonds. With some exceptions, these "dangling" bonds make free radicals highly chemically reactive towards other ...
