$Pb$

Vedclass · Answer

(C) In the carbon family (Group $14$),the density of elements increases as we move down the group due to the increase in atomic mass being more significant than the increase in atomic volume. Thus,$Pb$ has the highest density among the given options.Conversely,the boiling point decreases as we move down the group because the metallic character increases and the strength of interatomic forces (covalent bonding) decreases with increasing atomic size. Therefore,$Pb$ has the lowest boiling point among the given options.Hence,$Pb$ is the correct answer.

Among the following options,the element with the highest density and lowest boiling point is
