Concept explainers
Interpretation:
The reason for silver being a good conductor of electricity needs to be explained.
Concept introduction:
Conductivity refers to the aspect that energy can be transmitted. Metals are said to be good conductors of electricity. This is due to the fact that electrons are free to move around in metal structure. These electrons are not strongly held to the lattice points.
Answer to Problem 94A
Silver is good conductor of electricity as it is a metal and has delocalized electrons that can move. Hence, it can conduct electricity.
Explanation of Solution
Metallic bonds are formed when metal ions are surrounded by sea of electrons. It occurs between two metals. Its ionisation energy is low. Due to the presence of empty orbitals, the metal atoms overlap their valence orbitals and lose their valence electrons.
Silver belongs to group 11 and period 5. It has large atomic radii. Hence, there is one valence electron and it is farther from force of attraction of the nucleus. Therefore, the nucleus has less influence on the outermost electron. These electrons can move easily. When current is passed through, it moves from one electrode to other and hence is a good conductor.
Silver is good conductor of electricity as it is a metal and has delocalized electrons that can move. Hence, it can conduct electricity.
