Question

what is metal.........​

Answer 1

Answer:

Metal

Explanation:

Metals are materials holding or possessing the characteristics of being shiny, hard, fusible, malleable, ductile, etc. Few examples of metals (materials)  are – Gold, Silver, Aluminium, Copper, Iron, etc. 

The physical properties of metals are: 

 Luster

The property of metals which in the pure state usually shines. The shine on the metallic surface is the metallic luster. They shine in light due to the reason that the metals possess free electrons that vibrates on getting in contact with light. 

Malleability

Malleability refers to the property of metals by which they can be beaten into thin sheets. One such example is silver metal beaten to make silver foil used for decorating sweets.

Ductility

Ductility refers to the properties of metals by virtue of which they can be drawn into thin wires. One example of ductility is copper and iron which can be drawn in to thin wires.

 Conductivity

The metals are a good conductor of heat and electricity as they can pass through them. They are good conductors of heat and electricity. The best conductors of electricity are silver and copper, however, lead and mercury are poor conductors of electricity. They also have a high melting point except Caesium and Galium have the very low melting point.

Sonorous

On being struck hard, the metals produce a ringing sound. Due to this property, they sonorous. For example – the school bell produces a loud ringing sound when stuck with the hammer hard.  Some examples are – Iron, Gold, Copper, Aluminium, Magnesium, and many more.

Solid

Except for Mercury, all the metals are solid. Mercury is in the liquid state at room temperature. The exceptional metals are Sodium ( Na), Potassium ( K ) and Mercury. The metals like Sodium ( Na) and Potassium ( K ) are easily cut with the help of a knife. Other examples of metals are iron, copper, silver, aluminum, calcium, gold etc.
