1.	The alkali metals are low melting . Which of the following alkali metals is expected to melt if the room temperature rises to 30^(@)C ?
Answer» NA K Rb CS Solution :Among alkali metals, m.p. decreases as the strength of metallic bonding decreases with increasing size of the atom . Thus , Cs has the lowest m.p. and MELTS at `30^(@)`C.
