physical properties of metals
Answers
Answer:Metals are a good conductor of electricity which means that they can conduct electricity due to the free moving electrons present in them. Copper is used as wiring as it is a good conductor of electricity.
Metals have high melting points and high boiling points as they have strong metallic bonds.
All metals are physically lustrous. They have a lustre that makes them shine. Gold is used for making jewellery.
Metals are hard, they can’t be broken easily and require a lot of energy and strength to break. Iron is used to make cars, buildings, ships, etc.
Metals weigh a lot as they have a high density. Metals are heavy for their size.
They don’t have flexibility and have tensile strength. Metals can’t be stretched.
Metals are great conductors of heat. That’s why pots, pans, vessels are made of metals.
Some More Properties
They are good conductors of sound. They are sonorous.
Metals are ductile which means that they can be used to make thin wires.
They are malleable which means that they can be pounded into thin sheets.
Metals are usually solid at room temperature. However, there is an exception i.e. Mercury which is usually in liquid form.
There are a few metals that have low density, soft, and have low melting and boiling points. These metals are alkali and alkaline earth metals, they are also highly reactive, and are rarely encountered in their elemental, metallic form.
Some metals like sodium are so soft that they can be cut with a knife.
