WebFeb 8, 2024 · What is the trend in reactivity in Group 1 and 7? The non-metal elements in Group 7 – known as the halogens – get less reactive as you go down the group. This is the opposite trend to that seen in the alkali metals in Group 1 of the periodic table . Fluorine is the most reactive element of all in Group 7. 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.
