A) due to \[{{d}^{10}}\] configuration, metallic bonds are strong.
B) due to \[{{d}^{7}}\] configuration, metallic bonds are weak.
C) due to \[{{d}^{5}}\] configuration, metallic bonds are weak.
D) None of these
Correct Answer: C
Solution :
Due to \[{{d}^{5}}\] 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.You need to login to perform this action.
