Answer:
Chlorine takes electrons from potassium in the reaction.
Explanation:
2K + Cl₂ ⟶ 2KCl
The KCl is an ionic solid.
It consists of K⁺ and Cl⁻ ions that are formed by the transfer of an electron from K to Cl.
The chlorine takes electrons from potassium, and Gain of Electrons is Reduction.
At the same time, potassium loses electrons to chlorine, and Loss of Electrons is Oxidation.
Both oxidation and reduction are occurring, so this is an oxidation-reduction reaction.
