321614
Which have melting points below \(500^{\circ} \mathrm{C}\) ?
1 \(\mathrm{Ag}, \mathrm{Cu}\)
2 \(\mathrm{Zn}, \mathrm{Cd}\)
3 \(\mathrm{Cd}, \mathrm{Cu}\)
4 \(\mathrm{Ag}, \mathrm{Zn}\)
Explanation:
\(\mathrm{Zn}\) and \(\mathrm{Cd}\) both have completely filled outermost shells, and they cannot form covalent and metallic bonds strongly and show melting points less than \(500^{\circ} \mathrm{C}\) \(\left[\mathrm{Zn}\left(419.5^{\circ} \mathrm{C}\right)\right.\) and \(\left.\mathrm{Cd}\left(321^{\circ} \mathrm{C}\right)\right]\)

Transition element which is volatile among the following is
1 \(\mathrm{\mathrm{Zn}}\)
2 \(\mathrm{\mathrm{Cd}}\)
3 \(\mathrm{\mathrm{Hg}}\)
4 All
Explanation:
\(\mathrm{\mathrm{Zn}, \mathrm{Cd}, \mathrm{Hg}}\) have low melting and boiling points so they are volatile.
