CHXII08:THE D- & F-BLOCK ELEMENTS

321614 Which have melting points below $500^{\circ} C$ ?

1

Ag, Cu

2

Zn, Cd

3

Cd, Cu

4

Ag, Zn

Explanation:

$Zn$ and $Cd$ both have completely filled outermost shells, and they cannot form covalent and metallic bonds strongly and show melting points less than $500^{\circ} C$
$[Zn ({419.5}^{\circ} C)$ and $Cd (321^{\circ} C)]$

321615 Transition element which is volatile among the following is

1

Zn

2

Cd

3

Hg

4 All

Explanation:

$Zn, Cd, Hg$ have low melting and boiling points so they are volatile.
