a. Oxides and peroxides of alkali metals are diamanetic and colourless. b. Superoxides of the alkali metals are paramagnetic. c. Li is the least electronegative alkali metal. d. Potassiumis the most abundant alkail metal in the erth's crust. e. LiCI_(2) and MgCI_(2) are deliquesent. f. Lithium reacts with nitrogen to form nitride.

Assertion : Superoxides of alkali metals are paramagnetic. Reason : Superoxides contain the ion O_(2)^(-) which has one unpaired electron.

Assertion : Superoxides of alkali metals are paramagnetic. Reason : Superoxides contain the ion O_2^- which has one unpaired electron.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement - I : Superoxides of alkali metals are paramagnetic. Statement - II: Superoxides contain the ion which has one unpaired electron.
