The melting point of copper is higher than that of zinc because-
A
Copper has a bcc structure
B
The atomic volume of copper is higher
C
The d-electrons of copper are involved in metallic bonding.
D
The s as well as d electrons of copper are involved in metallic bonding.
Answer
The d-electrons of copper are involved in metallic bonding.
Explanation
Solution
In case of copper d-electrons are involved in metallic bonding that’s why m.pt. of Cu is higher than that of Zn.
