In which of the properties listed below, hydrogen shows similarity with halogens?
A. Nature of the oxide
B. Electropositive character
C. Combination with alkali metals
D. Atomicity
A and B
C and D
D only
C only
Hydrogen forms a neutral oxide, i.e., (water) while the oxides of halogens are acidic in nature.
Hydrogen shows electropositive nature while halogens are electronegative in nature.
On combination with alkali metals, Hydrogen forms uninegative ion H– and halogens also uninegative ion form X–. Hydrogen also exists in diatomic form as halogens do.
