Question

Explain the reosons for all the physical properties of metals

Answer 1

Explanation:

physical properties of metals :-

1: metals are malleable eg:- aluminium, copper etc...

2: metals are ductile eg:- gold, silver copper etc...

3: metals are good conductors of heat and electricity eg:- silver, copper etc...

4: metals are lustrous eg:- gold, silver etc...

5: metals are generally hard eg:- iron, aluminium etc...( sodium and phosphorus are soft )

6: metals are solid at room temperature eg:- silver, gold etc...( except mercury )

7: metals have high densities eg:- iron, gold etc...( except potassium and sodium)

8: metals are sonorous eg:- copper, gold etc...

9: metals have usually grey and black color eg:- iron, silver etc...( except gold and copper )

10: metals have normally high melting point eg:- iron, copper etc... ( except sodium and potassium )

Answer 2

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.
