As you go down the alkali metals group, the elements become m â¦ ore reactive. So Francium is the most reactive alkali metal. Also, Halogens, because they already have 7 electrons and only need to gain one in order to have a stable valence level of 8. As you go up the halogens group, the elements become more reactive.
The Most Reactive and Least Reactive Metals. 1  The higher the metal in the series, the more reactive it is i.e., its reaction is fast and more exothermic. 2  This also implies that the reverse reaction becomes more difficult i.e., the more reactive a metal, the more difficult it is to extract from its ore.
