How is atomic radius related to the reactivity of metals and non-metals?

Metals: Larger atomic radius → outer electrons are farther from the nucleus → easier to lose electrons → reactivity increases. 

Non-metals: Smaller atomic radius → stronger pull on incoming electrons → easier to gain electrons → reactivity increases.
