$(I)$ they exhibit high enthalpies of atomisation as the $d-$ subshell is full
$(II)$ $zn$ and $Cd$ do not show variable oxidation states while $Hg$ shows $+ I$ and $+ II$
$(III)$ Compound of $Zn,\,Cd$ and $Hg$, are paramagnetic in nature
$(IV)$ $Zn,\,Cd$ and $Hg$ are called soft metals
$CS_2 + 3O_2 \,\,\to \,\, 2SO_2 + CO_2$
