Explain why sodium (Na) will form an ionic bond with chlorine (Cl) but not with potassium (K).
borishaifa [10]

They are both metals

Explanation:

Sodium and Potassium cannot form ionic compounds because they are both metals.

Metals do not form ionic bonds between themselves.

To form an ionic bond;

  • Two atoms combines together in which one of them transfers its valence electrons to the other.
  • The atoms must have a large electronegativity difference between them.
  • Formation of ions which causes electrostatic attraction.
  • The ions formed are oppositely charged so that attraction is possible.

The description above is only satisfied by metals and non-metals.
