Aluminum fluoride is AlF3. It has 3 fluorine atoms for each aluminum atom.
aluminum cloride
ionic bonding
Aluminum and Nitrogen create a compound named aluminum nitride, its Chemical formula is AlN
Sodium and fluorine will form an ionic compound named sodium fluoride with the formula NaF.
Al3+ and Br- together make, AlBr3
AlF3
Pure fluorine usually exists as a diatomic compound, formula F2.
It would be, if it were covalent. However, due to the large difference in electronegativity, any compound of aluminum and fluorine would be ionic. This compound would then be called aluminum IV fluoride. Aluminum does not readily form a 4+ ion, but rather forms a 3+ ion, so the correct formula for aluminum fluoride is AlF3.
CaF2
aluminum cloride
The formula for the compound aluminum chlorate is AlCl3O9 .
Al2S3 is the correct formula for aluminum sulfide.
Surely meant: AlCl3 for aluminum chloride
ionic bonding
There is no compound with the formula Al2Cl3. But AlCl3 is aluminum chloride.
Al2(CO3)3
Aluminum and Nitrogen create a compound named aluminum nitride, its Chemical formula is AlN
