Reactivity Series: Reactive Metals

The video explores the reactivity series and its influence on human history. It explains how metals like gold and silver, being unreactive, were used early in history, while more reactive metals like copper, tin, and iron marked significant technological ages. The video also discusses modern extraction methods for highly reactive metals, highlighting the role of electrolysis.
