Facts about the History of the Barium
Element
Properties within each individual group are similar, but
nevertheless vary within a group. Generally chemical activity
decreases as the period increases a non-metal group and increases
as the period increases within a metal group. The first element in
a group is always an active metal, the last is always an inactive
non-metal.
