Following are some properties of hydrogen. Which of the following properties resemble with alkali metals and which with halogens
(i) Hydrogen lose one electron to form unipositive ions
(ii) Hydrogen gain one electron to form uninegative ions
(iii) Hydrogen forms oxides, halides and sulphides
(iv) Hydrogen has a very high ionization enthalpy
(v) Hydrogen forms a diatomic molecule, combines with elements to form hydrides and covalent compounds.

(v) Hydrogen forms a diatomic molecule, combines with elements to form hydrides and covalent compounds.
View answer and explanation
Correct option: C
Alkali metals resemble (i) and (iii)
Halogens resemble (ii), (iv) and (v)
Halogens resemble (ii), (iv) and (v)
The correct answer is B because alkali metals lose electrons and form oxides, while halogens gain electrons, form halides, and exist as diatomic molecules.
