Answer

Step 1 — Write each symbol with its valency

K1+↗Cl1−\text{K}^{1+} \phantom{\nearrow} \text{Cl}^{1-}

Step 2 — Interchange the valencies

K21 ↘↙ Cl1⇒K11 ↘↙ Cl1\overset{\phantom{2}{1}}{\text{K}} \space {\searrow}\mathllap{\swarrow} \space \overset{1}{\text{Cl}} \Rightarrow \underset{\phantom{1}{1}}{\text{K}} \space {\searrow}\mathllap{\swarrow} \space \underset{1}{\text{Cl}}

Step 3 — Write the interchanged number & hence the formula

Therefore, we get

Formula of Potassium chloride : KCl\bold{KCl}
