Among the following metals, which has the lowest boiling point?
Cadmium
The boiling point of a metal reflects how strongly its atoms are bonded; weaker metallic bonding lets the metal vaporise at a lower temperature.
Comparing the four choices by their known boiling points helps identify the weakest-bonded metal.
Cobalt boils near 2927°C and aluminium near 2470°C, both very high because of strong metallic bonding.
Calcium boils near 1484°C, lower than those two but still well above the last option.
Cadmium boils at only about 767°C, far below the others, because its atoms are held together by comparatively weak metallic bonds.
Therefore, of cobalt, calcium and aluminium, none reaches as low a boiling point as cadmium, so cadmium is the metal that vaporises most easily.
Hence, the answer is Cadmium.
