Which of the following statement is/are correct in regard to alloys as compared to pure metals?
Which of the following statement is/are correct in regard to alloys as compared to pure metals?
The correct option is C Low melting point and low conductivity
Pure metals are better conductors of electricity than alloys because when other elements are added to pure metals they restrict the flow of electrons.
Example:- Brass, an alloy of copper and zinc (Cu and Zn) and bronze, an alloy of copper and tin (Cu and Sn) are not good conductors of electricity whereas copper is widely used for making electrical circuits as it is an excellent conductor.
In alloys, the atoms are of different sizes and their arrangement is less regular than a pure metal. This makes the bonds between the atoms very weak and lowers the melting point.
Example:- Solder, an alloy of lead (Pb) and tin (Sn) has a low melting point and is used for welding electrical wires together.
