They do not break up to form ions.

The electrostatic force of attraction between oppositely charged ions.

A σ bond is formed by the end-on overlap of orbitals, while a π bond is formed by the sideways overlap of p-orbitals.

<p>An atom is a neutral particle, whereas an ion is a charged atom or group of atoms. In ionic bonding, ions with opposite charges attract each other, forming an electrostatic force of attraction.</p> Signup and view all the answers

<p>Valency is the number of bonds an atom of an element forms when it reacts, and it determines the number of bonds an element can form to achieve a stable electronic arrangement.</p> Signup and view all the answers
