Question

Assertion :Alkali metals are strong reducing agents, while halogens [non-metals], are strong oxidising agents. Reason: Metals have 1,2 or 3 valence electrons so they always ionize by losing electrons while non metals have 4, 5, 6 or 7 valence electrons so they ionize by gaining electrons.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Metals have 1,2 or 3 valence electron so they always ionize by losing electrons while non metals have 4, 5, 6 or 7 valence electron so they ionize by gaining electrons.
$Na-e^{-}\to N{a}^{+}$
$Cl+e^{-}\to C{l}^{-}$
So metal acts as reducing agents while non metals acts as oxidising agents.
