Question
In first transition series, the melting point of 
is low because
- Due to
configuration, metallic bonds are strong
- Due to
configuration, metallic bonds are weak
- Due to
configuration, metallic bonds are weak
- None of these
configuration, metallic bonds are strong
configuration, metallic bonds are weak
configuration, metallic bonds are weak
The correct answer is: Due to configuration, metallic bonds are weak
Due to configuration, metallic bonds are weak. orbital is half filled as a result 
electrons are more tightly held by the nucleus and this reduces the de-localization of electrons resulting in weaker metallic bonding.
