Question

Oxidation is defined as.

• A. Loss of electrons
• B. Gain of electrons
• C. Gain of protons
• D. Loss of protons

Answer 1

The correct option is A Loss of electrons

Oxidation is the process in which there is a loss of electrons. For example, in the following reaction, magnesium looses 2 electrons to form magnesium ion. Hence, magnesium gets oxidised in this half-ionic reaction.

$Mg\to {Mg}^{+2}+{2e}^{-}$

Hence, correct answer is A.
