Why does the reactivity increase in group 1? - KnowledgeBurrow

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. WebApr 13, 2024 · Explanation: As the size of the metal cation increases down the group, the lattice energy of the hydrides decreases down the group. Consequently, the reactivity of the alkali towards hydrogen decreases down the group. iii. The ionic character of the alkali metal hydrides increases from Li to Cs. biourn treesWebGroup 1 elements need to lose one electron when they react. As you go down group one there are more energy shells so more distance between the outer electron and the nucleus This means the outer electron is less attracted to the nucleus going down group 1 Therefore it is easier to lose the outer electron as you go down the group dale earnhardt belt with buckle
