configuration, metallic bonds are strong
B
due to 
configuration, metallic bonds are weak
configuration, metallic bonds are weak
C
due to 
configuration, metallic bonds are weak
configuration, metallic bonds are weak
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
C
Due to 
configuration, 
has exactly half filled 
-orbitals. As a result the electronic configuration is stable means 
electrons are more tightly held by the nucleus and this reduces the delocalization of electrons resulting in weaker metallic bonding.
