Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Generally, 3d transition metals have high melting points. Reason R : Involvement of 3d-electrons in addition to 4s-electrons in the interatomic metallic bonding. In light of the above statements, choose the most appropriate answer from the options given below:
A
Both A and R are correct and R is the correct explanation of A
B
Both A and R are correct but R is NOT the correct explanation of A
C
A is correct but R is not correct
D
A is not correct but R is correct
Explanation
In d-block metals, unpaired electrons of (n−1) d subshell also participate in metallic bonding along with ns that's why interatomic metallic bonding is comparatively strong hence their melting point are high
