Question

What could not form an ionic compound

Answer 1

Step-by-step explanation:

Ionic bonds are not formed by atoms that find it difficult to obtain or lose electrons from their outermost orbit.

Example: silicon and carbon.

Answer 2

As ozone is tri-atomic molecule, made up of the 3 O-atoms, hence, as all atoms are same. Ozone has coordinate bond hence these can not form the ionic compound. While all others are ionic compound.
