APA TEGESÉ FREE RADICAL ING BASA INGGRIS?

Radikal (kimia)

Radical (chemistry)

Ing babagan kimia, radikal yaiku sawijining atom, molekul, utawa ion sing nduweni elektron valensi sing ora duwe pasangan utawa cangkang elektron sing mbukak, lan mulane bisa uga diarani minangka gadhah siji utawa luwih "ikatan" ikatan kovalen. Kanthi sawetara sèkrèsi, obligasi iki "njlentrehake" nggawe radikal bebas sing reaktif banget marang zat liya, utawa malah marang awake dhewe: molekul-molekul bakal kerep dimereni utawa polimer nalika lagi gegandhen. Paling radikal sing cukup stabil mung ing konsentrasi banget ing media inert utawa ing vakum. Conto penting radikal bebas yaiku radikal hidroksil, sawijining molekul sing dadi salah siji saka atom hidrogen sing cendhak saka molekul banyu lan kanthi mangkono duweni siji "ikatan" saka oksigen. Rong conto liyane yaiku molekul karben, sing duweni rong ikatan rangkap; lan anion superoxide, molekul oksigen O 2 karo siji elektron ekstra, sing duweni siji ikatan rangkep. Saliyane, anion hidroksil, anion oksida lan kation karbenium ora minangka radikal, amarga ikatan kasebut uga bisa dipungkiri dening nambah utawa ngilangi elektron.

In chemistry, a 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 substances, or even towards themselves: their molecules will often spontaneously dimerize or polymerize if they come in contact with each other. Most radicals are reasonably stable only at very low concentrations in inert media or in a vacuum. A notable example of a free radical is the hydroxyl radical, a molecule that is one hydrogen atom short of a water molecule and thus has one bond "dangling" from the oxygen. Two other examples are the carbene molecule, which has two dangling bonds; and the superoxide anion, the oxygen molecule O 2 with one extra electron, which has one dangling bond. On the other hand, the hydroxyl anion, the oxide anion and the carbenium cation are not radicals, since the bonds that may appear to be dangling are in fact resolved by the addition or removal of electrons.
