- (T, T) Lithium replaces any other metal in a single replacement reaction;
therefore, it is the most active metal. It’s also true that lithium has only one
electron in its outer energy level. Although lithium’s outer configuration of
only one electron aids in its high activity, it is not the only reason for its high
activity. Other metals (like sodium and potassium) have only one electron in
their outer energy levels and are fairly active, but they aren’t as active as
lithium.
