The melting and boiling points of Zn , Cd and Hg are low. Why ? Or Wh – InterviewSolution

1.	The melting and boiling points of Zn , Cd and Hg are low. Why ? Or WhyZn , Cd and Hg are soft and have low m.pt. ?
Answer» SOLUTION :In Zn, Cd and Hg, all the ELECTRONS in d-subshell are PAIRED. Hence, the metallic bonds present in them are weak . That is why they have low melting and boling points.
