Question

Choose the chemical properties of metals and non-metals with reference to electrochemical nature.

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

Answer 1

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

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.

In case of metal -
$Na-e^{-}\to N{a}^{+}$

In case of non-metal -
$Cl+e^{-}\to C{l}^{-}$

So, metal acts as a reducing agent while non-metal acts as an oxidising agent.

Hence, option $C$ is correct.
