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, Mn has exactly half filled d-orbitals. As a result the electronic configuration is stable means 3d electrons are more tightly held by the nucleus and this reduces the delocalization of electrons resulting in weaker metallic bonding.
