Chemistry: The Periodic Table and Periodicity
... What is the general trend of reactivity for non-metals within a group and a period? Why? Reactivity decreases as you go down a group, because there are more shells making it harder for the nucleus to pull electrons closer to the nucleus. Reactivity increases as you go across a period because electro ...
