Question

How are the ions in Potassium chloride bonded to each other?

Answer 1

Bonding in Potassium chloride:

• Potassium chloride$\left(\mathrm{KCl}\right)$ is formed due to the formation of the ionic bonds between Potassium$\left({\mathrm{K}}^{+}\right)$and Chlorine ion$\left({\mathrm{Cl}}^{-}\right)$.
• When the electron in the valence shell of the Potassium atom is transferred to the valence shell of the Chlorine atom then both the atoms complete their octet, and the ionic bond gets formed between them.
• The oppositely charged ions formed ${\mathrm{K}}^{+}$ and ${\mathrm{Cl}}^{-}$are then attracted to each other by a strong electrostatic force of attraction, known as an Ionic bond or electrovalent bond.
• The figure showing the formation of the ionic bond between the ions of Potassium chloride is given by:

Hence, Since the electron gets transferred between the two atoms during the formation of Potassium chloride, the ions in Potassium chloride bonded to each other by Ionic bonding.
