The melting point of alkali metal is _____________(a) depends on the a

1.	The melting point of alkali metal is _____________(a) depends on the atmosphere(b) low(c) high(d) zeroI got this question in class test.My question is taken from s-Block Elements topic in chapter s-Block Elements of Chemistry – Class 11
Answer» The correct option is (b) low To explain I would say: The melting and boiling POINTS of alkali metals are quite low and they decrease down the group due to WEAKENING of their metallic bonds. Francium is the only ELEMENT in this group which is a LIQUID at ROOM temperature.
