Answer:
Step-by-step explanation:
Ionic bonds form between two or more atoms by the transfer of one or more electrons between atoms. Electron transfer produces negative ions called anions and positive ions called cations. These ions attract each other.
Explanation: An ionic bond is formed because sodium is a part of the Alkali metals and Oxygen is a non-metal and a gas. 4Na + O2 → 2Na2O (s) OR Na + O2 → NaO2 (s).
