In Chemistry, the Reactivity Series (Activity Series) ranks metals from most reactive to least reactive. The position of a metal determines how it reacts with water, acids, and oxygen.
The least reactive metals — Gold (Au) and Platinum (Pt) — are found in nature in their pure form because they don't react with air or water.
Among commonly studied metals:
Potassium (K) > Sodium (Na) > Calcium (Ca) > Magnesium (Mg) > Aluminium (Al) > Zinc (Zn) > Iron (Fe) > Lead (Pb) > Copper (Cu) > Silver (Ag) > Gold (Au)

Sodium (Na) is highly reactive and reacts violently with water and even atmospheric moisture. Storing it in kerosene (an organic liquid) prevents contact with water or air.
