WebThe bonding in carbon dioxide (CO 2 ): all atoms are surrounded by 8 electrons, fulfilling the octet rule. The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. WebFree radicals are very reactive species ('species' here refers to a molecule or atom). Most reactions occur with a pair of electrons reacting. However, free radicals have a lone electron....
