Question

Define oxidation.

Answer 1

Oxidation - When a substance gains oxygen or electronegative radical or loses hydrogen or electropositive radical that is called oxidation.

Example -The oxidation of magnesium (Mg) involves the chemical reaction between magnesium metal and oxygen (O₂) to form

$$\begin{gathered} \mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2\mathrm{MgO}\left(\mathrm{s}\right) \\ \mathrm{Magnesium}\mathrm{Oxygen}\mathrm{Magnesium}\mathrm{oxide} \end{gathered}$$
