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:
B. Both A and R are correct and R is the correct explanation of A .
Assertion A is correct because transition metals generally have high melting points due to strong metallic bonding. Reason R is correct and explains Assertion A because the strong metallic bonding in 3d transition metals is attributed to the involvement of a greater number of electrons from the 3d subshell in addition to the 4s electrons in the interatomic metallic bonding. Thus, both A and R are correct and R is the correct explanation of A. Answer: Both A and R are correct and R is the correct explanation of A .
