Reactivity going down group 7

WebJan 30, 2024 · As you go down a group, electronegativity decreases because the bonding pair of electrons is increasingly distant from the attraction of the nucleus. Consider the hydrogen fluoride and hydrogen chloride molecules: The bonding pair is shielded from the fluorine's nucleus only by the 1s 2 electrons. WebAs you go down group 1 (the alkali metals) in the periodic table, the elements get more reactive. As you go up group 7 (the halogens), again the elements get more reactive. Is as follows: To remember how the reactivity of the alkali metals and halogens increases or decreases, put a pin in the middle of the periodic table and spin it anti-clockwise.
