Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. oxygen and sulfur are non-metals, indicating that the bond formed between these two atoms cannot be ionic. If atoms have similar electronegativities (the . In the solid state it adopts an 'ionic lattice' structure with octahedral coordination for the $\ce{Al^{3+}}$ ions but in the liquid and gas phases it exists as a covalent compound, either as $\ce{AlCl3}$ or as a dimer $\ce{Al2Cl6}$. Hence, the bond formed between these two atoms is covalent. Most chemists agree that an electronegativity difference greater than 1.7 renders a bond ionic. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds . In this section, we will study more about the difference between these two bonds.
