Alkali Metals Melting Which Following Alkali Metals Expected Room Temperature Rises 30в°C

The alkali metals are low melting. Which of the following alkali metals is expected to melt if the room temperature rises … (b) K …

Answers:

(d) Among alkali metals, melting point decreases as the strength of metallic bonding decreases with increasing size of the atom. Thus, Cs has the lowest melting point (28.5°C) and will melt at 30°C.
