Metal is a material that is usually hard and shiny. It is commonly used in many objects and tools. Metals are excellent conductors of heat and electricity, which means they can transfer energy effectively.
History
The use of metals began thousands of years ago. Early humans discovered metals like gold, silver, and copper. They used these metals for making tools, jewelry, and coins. The Bronze Age, starting around 3300 BCE, saw the use of bronze, an alloy of copper and tin, for tools and weapons. Later, during the Iron Age, iron became widely used, greatly advancing construction and manufacturing techniques.
