WebGroup 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 WebAug 3, 2024 · These observations show that there is a trend in reactivity in group 1. As you descend through group 1, the elements become more reactive with oxygen. ... As we go down group 1, the outer electrons become easier to lose and so the alkali metals become more reactive. Using trends to predict properties.
