Final answer:
Metals have properties that make them good electrical conductors, thermal conductors, and possess other useful characteristics. They are also categorized as electrical conductors and thermal conductors. Magnetism is another property that some materials, including metals, may possess.
Step-by-step explanation:
Metals are good electrical and thermal conductors, they have a shiny lustre, they are malleable and ductile, and they have a high melting point. Metals also have a high density. These properties make metals very useful in electrical wires, cooking utensils, jewellery and many other applications.
Matter can also be classified into electrical conductors, semi-conductors and insulators. An electrical conductor allows an electrical current to pass through it. Most metals are good electrical conductors. An electrical insulator is a non-conducting material that does not carry any charge. Examples are plastic, wood, cotton material and ceramic.
Materials may also be classified as thermal conductors or thermal insulators depending on whether or not they are able to conduct heat. Materials may also be magnetic or non-magnetic. Magnetism is a force that certain kinds of objects, which are called 'magnetic' objects, can exert on each other without physically touching. A magnetic object is surrounded by a magnetic 'field' that gets weaker as one moves further away from the object.
