Question

Assertion (A): The metals and alloys are good conductors of electricity.
Reason (R): Bronze is an alloy of copper and tin and it is not a good conductor of electricity.
Check whether the statement and Reason is correct or not.

Answer 1

Hint: Conductors are substances which carry electric charge. The presence of electrons flow the electric charge from one point to another.

Complete answer:
A metal is a substance which is malleable and ductile and conducts heat and electricity well. Metals are elements which have the tendency to lose their valence electrons. Due to the presence of free electrons around the metal atom, the electrons carry the electric charge in various directions.
The electrons move in different directions inside the metals. The movement of electrons is responsible for the transfer of electric charge from one point to another.
Alloys are composed of metals, carbons and other constituents like various elements. Alloys serve a wide range of properties like corrosion resistant, hardness, magnetism, ductility and enrich toughness. Beside this as they consist of metals and alloys also conduct electricity.
The metals present in alloys consist of free electrons and so they are good conductors of electricity. The bronze consists of copper and tin in which both are metals. Hence they are good conductors of electricity.
Hence Assertion (A) is correct and Reason (R) is incorrect.

Note: An alloy is a substance which is made up of a combination of two or more elements. Of the elements present in alloys one is a metal. An alloy is a homogeneous mixture of metal and non metal but the properties of metals are retained in the alloy.
