How reactive is astatine
NettetThe halogens are a group in the periodic table systematically known as group 17. It consists of fluorine, chlorine, bromine, iodine, astatine, and tennessine. The halogens generally show many of the properties typical of non-metals. They are poor conductors and have low melting and boiling points. Nettet19. mar. 2024 · All of the garden-variety halogens from fluorine to iodine make halogen bonds, with larger halogens forming stronger bonds.

The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of …
NettetThe great reactivity of fluorine largely stems from the relatively low dissociation energy, a standard measure for bond energies, of the F―F bond (37.7 kilocalories per mole) and its ability to form stable strong bonds with essentially all the other elements.
