Just take a look around your house and you will surely find at least ten items made of metal. Your house keys, car, gold ornaments, some of the utensils in the kitchen…the list will go on and on. We now know some of the uses of metals. But what are metals?
Metals are opaque, lustrous elements that are good conductors of heat and electricity. There are more than 100 chemical elements, and most of them are metals. These elements are hard, strong and are good conductors of heat and electricity. Metals can be made into useful shapes without breaking or cracking. Some metals are light while some others are heavy. They can combine with oxygen and other non-metals as well.
Metals are an important part of the modern world. They are present everywhere, ranging from safety pins to spacecraft. Our life would have been so different if we did not have metals.
