Group 2 metals. From the left: beryllium, magnesium, calcium, strontium and barium. Each element in this group has a tendency to lose two electrons. Therefore, these elements are chemically reactive. Their reactive increases from left to right and so beryllium is the least reactive and barium is the most.
