Reactivity of metals down a group
WebJul 15, 2024 · Why reactivity of metals increase down group? As we go down the group, the atom gets bigger. The bigger the atom, the further away the last electron. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity. WebMetal reactivity decreases from left to right across periods and increases down groups. nonmetallic characteristics increases from left to right and decreases down groups. Nonmetal reactivity increases from left to right and decreases down groups. For example, the following trends are observed for alkali metals: Atomic radii: Li < Na < K < Rb < Cs;
