It is known that the reactivity of group 7 elements decreases down the group. The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity in the higher periods. Of course there are few exceptions to this rule. Reactions are mostly Exothermic in case of highly reactive metals. And the majority of oxides are insulators or semiconductors.
