Question

Why the melting point of Pb is greater than Sn?​

Answer 1

Answer:

Hey!

This page explores the trend from non-metallic to metallic behaviour in the Group 4 elements - carbon (C), silicon (Si), germanium (Ge), tin (Sn) and lead (Pb). It describes how this trend is shown in the structures and physical properties of the elements, and finally makes a not entirely successful attempt to explain the trend.

Answer 2

Answer:

The trends reflect the increasing weakness of the covalent or metallic bonds as the atoms get bigger and the bonds get longer. The low value for tin's melting point compared with lead is presumably due to tin forming a distorted 12-co-ordinated structure rather than a pure one.
