उत्तर
The electrical conductivity and melting point of an alloy is less than that of pure metals.
Explanation:
Alloys have an irregular crystal structure because the different-sized atoms of the added elements disrupt the neat rows of the host metal. This distorted lattice scatters electrons, which reduces the material’s electrical conductivity compared to pure metals. Additionally, the irregular arrangement weakens uniform interatomic bonding, allowing the structure to break apart at a lower melting point than that of its pure metallic components.
