Group I: potassium ion

Added by Lawrie Ryan on Feb 27, 2008

An animation explaining the reactivity of Group I elements. As you descend the group, the outer electrons become less and less tightly bound and hence become more reactive. Potassium is more reactive than lithium.

This resource is from the unit Explaining the Reactivity of the Alkali Metals which is part of Absorb Chemistry.
