WebChemical reactivity of group 17 elements decreases down group 17 from top to bottom. First ionization energy decreases down group 17 from top to bottom. Melting point and boiling point increase down Group 17 from top to bottom. Elements become darker in colour going down group 17 from top to bottom. WebOne of the other reasons that the Halogens decrease in reactivity down the group as the size of the atomic radius increases with an increase in the electronic energy level. As, down …
WebFeb 11, 2024 · The chemical reactivity of these elements increases down the group. Reactions with Oxygen (Air) The alkali metals tarnish in dry air. It is due to the formation of their oxides which in turn reacts with moisture to form hydroxides. Alkali metals burn vigorously in oxygen forming oxides. Lithium forms monoxide, \((Li_2O)\) sodium forms … WebPeriod - reactivity increases as you go from the left to the right across a period. Group - reactivity decreases as you go down the group. Why? The farther right and up you go on the periodic table, the higher the electronegativity, resulting in a more vigorous exchange of electron.
