How are bonds formed in iodine
Iodine is the fourth halogen, being a member of group 17 in the periodic table, below fluorine, chlorine, and bromine; it is the heaviest stable member of its group. (The fifth and sixth halogens, the radioactive astatine and tennessine, are not well-studied due to their expense and inaccessibility in large quantities, but appear to show various unusual properties for the group due to relativistic effects.) Iodine has an electron configuration of [Kr]4d 5s 5p , with the seven electr… WebThey are formed through an oxidative reaction in which the thiol groups of two cysteine residues are joined by a covalent bond. In contrast to other covalent bonds in proteins, disulfides can be reversed or isomerized by spontaneous or enzyme-catalyzed thiol:disulfide exchange reactions [2].
