Question 19 : Which of these elements behave partly as the alkaline metals as well as a halogen element?_____________
Helium
Fluorine
Hydrogen
Helium
Fluorine
Hydrogen
Expert's answer
Hydrogen behave partly as the alkaline metals as well as a halogen element!
For example:
a) Hydrogen in molecula water H 2 O behave as the alkaline metal: Na 2 O, Li 2 O. (Oxidation number of Hydrogen is +1);
b) Hydrogen in molecula lithium hydride LiH behave as a halogen element: LiF, LiCl. (Oxidation number of Hydrogen is -1).
Answer: Hydrogen.
