Sodium chloride is composed of molecules that are stable when dry. In water, the atoms of the molecules separate from each other
astra-53 [7]

The molecules of Sodium chloride holds a chemical bond to become stable when dry is an ionic bond.

<h3>What are chemical bonds?</h3>

The chemical bonds are those which holds the atoms of molecules together and creates a temporary connection between them.

The three major types of chemical bonds are:

  • Ionic bonds
  • Covalent bonds
  • Metallic bonds

<h3>What are ionic bonds?</h3>

The ionic bonds generally occurs in between a metal and a nonmetal ions.

The atoms share electrons in between them to become stable, forms ions. Due to electric attraction between these ions forms a bond between them. That bond is called as Ionic bond.

<h3>The type of chemical bond in Sodium chloride:</h3>

Sodium chloride - NaCl

Where Na(sodium) forms Na⁺ ion(metal) by sharing electrons with the chlorine atom and Cl(chlorine) forms Cl⁻ ion(non-metal).

So, due to the attraction between the anion and the cation, a bond is established between them. So, it is called Ionic bond.

Therefore, the chemical bond in Sodium chloride is an Ionic bond.
