Answer:

The correct answer is option C.

Explanation:

Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.

  • The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom.
  • This bond is usually formed between a metal and a non-metal.

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

From the given options , the option with metal and non metal is potassium and chlorine. these elements will combine together to form ionic compound called potassium chloride.
