NEET 2026 Chemistry question
Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R. Assertion A: Generally, 3 transition metals have high melting points. Reason R: Involvement of 3-electrons in addition to 4-electrons in the interatomic metallic bonding. In light of the above statements, choose the most appropriate answer from the options given below:
Answer: (1)
Solution
Assertion A is true: 3d transition metals (except Zn, Cd, Hg group) have high melting points. Reason R is true: in these metals the (n-1)d electrons also take part in metallic bonding along with the ns electrons, so the metallic bond is strong (more unpaired d electrons
