What is Active Metal?
An active metal is a metal that reacts readily with water, dilute acids, or air under ordinary conditions. Active metals are strong reducing agents and appear high in the activity series (electrochemical series). They include the alkali metals (Group 1) and alkaline earth metals (Group 2), as well as aluminium, zinc, and iron.

Lightweight structural alloys (aluminium, magnesium); reducing agents in metallurgy; batteries (lithium, zinc); fireworks and pyrotechnics (magnesium, sodium); chemical synthesis (sodium, potassium in organic reactions)
Highly reactive — alkali metals (Na, K, Li) react violently with water producing flammable H₂ gas and forming caustic hydroxides. Store under mineral oil or inert atmosphere. Alkaline earth metals are less reactive but still hazardous. Magnesium powder is a serious fire risk.
