Question
Potassium (at No.19) and chlorine (at No.17) react to form a compound. Explain the formation of the compound on the basis of reduction.
Solution
\[\ce{2K + Cl2 -> 2KCl}\]
In the electronic concept, a reduction is a process in which an atom or ion accepts electron(s).
\[\ce{Cl2 + 2e--> 2Cl-}\]
