Explain why :
metals are malleable and ductile,

Explain the meaning of malleable and ductile.

Select the property which is not for metals - A : Metals are good conductors of electricity B : Metals are malleable & ductile C: Non - polar covalent compounds are formed from metals D : Metals have 1, 2 or 3 valence electrons.

Assertion : Wrought iron is more malleable and ductile than steel. Reason : It contains slightly less percentage of carbon.

A solid is a good conductor of electricity. It is alos malleable and ductile. Predict its nature.

Identify the type of cyrstalline solid based on the following properties : (a) Conducts electricity in the molten state but in the solid state. (b) Very hard with melting point and acts as electrical insulator. (c) Conducts electricity in the solid state, malleable and ductile.
