Question

what lustrous materials explain why does iron appear diffirent from copper and silver???​

Answer 1

Explanation:

Copper is the most heavily used coinage metal due to its electrical properties, its abundance (contrasted to silver and gold), and the attractiveness of its alloys—brass and bronze.

Zinc is used in alloys with copper to create a harder metal known as brass.

In galvanization, zinc coats iron by oxidizing to form a protective layer of zinc oxide (ZnO) that protects the iron from rust.

Cobalt and nickel are trace elements with properties similar to iron.

Physical Material Properties of Metals

The many uses of Metals are: 

Metals are used for various purposes, from making wires and sheets. For example – Copper and aluminum wires in electrical equipment’s, especially for conduction of electricity.

Metals are also used in making automobiles, machinery, water boilers, industrial gadgets, etc.

The metals are used in making utensils and water boilers due to its property of being a good conductor of heat.

Non Metals

Non – metals are materials not holding the characteristics of metals, means they are not shiny, hard, fusible, malleable, ductile, etc. Many materials like coal and Sulphur are very soft and dull in appearance. They break down into very fine thin powdery mass on tapping with the hammer. They are neither in – sonorous and also are a very poor conductor of heat and electricity.  Few examples of non – metals are carbon, oxygen, Sulphur, etc.
