Why does the reactivity of group 1 elements increase down the group?
As you go down the group: - The atoms get larger - The outer electron gets further from the nucleus - The attraction between the nucleus and outer electron gets weaker, so the electron is more easily lost - Remember the electrons are attracted to the
