Question

According to electrochemical nature, what is true for a metal and a nonmetal?

• A. Both are reducing agent
• B. Both are oxidising agent
• C. Metal acts as reducing agents while non metals acts as oxidising agents
• D. Non metal acts as reducing agents while metals acts as oxidising agents

Answer 1

The correct option is C Metal acts as reducing agents while non metals acts as oxidising agents

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.
