Aluminium sulfide has an ionic bond but some authors consider this bond as polar covalent.
The name of the simple binary ionic compound Al2S3 is aluminum sulfide.
H2O is a molecular compound.
The ionic formula for Al3+ is Al^3+ and for S2- is S^2-. When these two ions combine, they form the ionic compound Al2S3.
The formula for the ionic compound formed from Al^3+ and S^2- ions will be Al2S3. This is because the charges must balance out, requiring two Al^3+ ions for every three S^2- ions to cancel out the charges and form a neutral compound.
