Because its a simple inorganic substance, ‘tri’ is superfluous because we know the valency of aluminium is (almost always) 3+ and thus we know there will be three chloride anions without even having to look at its formula.

What is the proper name for AlF3?
Aluminum fluoride (AlF3) is primarily used as an additive in the production of aluminum.
What type of compound is AlF3?
Aluminum fluoride | AlF3 – PubChem.
Why is Aluminium fluoride ionic?
In terms of electron arrangement in the formation of the ionic compound aluminium fluoride, the aluminium donates its three outer electrons to three fluorine atoms forming a triple positive aluminium ion and three single negative fluoride ions . ... Valency of Al is 3 and F is 1, i.e. equal to the charges on the ions.
How many F’s are needed to form aluminum fluoride?
We can see that the aluminum metal ion has a charge of +3 and the Fluoride ion has a charge of -1.To get the formula of the compound formed, we need to swap the charges of the two ions: 3 F – ions are needed to balance and cancel out the charge of Al 3 + .
How does aluminum fluoride form?
Aluminum fluoride forms a white, crystalline solid at room temperature. The crystal structure forms a rhombohedral. It has a melting point of 1290° C and is made by reacting alumina and hydrogen fluoride gas to break the aluminum-oxygen bond .
What is the correct name for Ca3P2?

Which is more covalent AlF3 or AlCl3?
Hence, by fajan’s rule AlCl3 has more covalent character , as compared to AlF3 which has less covalent and more ionic character. Since, AlF3 has ionic character or it forms an ionic bond, it cannot be electron deficient.
Which is more covalent AlF3 or albr3?
Answer: AlF3 is more ionic .In halogens down the group ionic character decreases. But covalent character increases. NOTE:LARGER CATION AND SMALLER ANION FORMS IONIC BOND.
Which is more covalent AlCl3 or cacl2?
According to the Fajan’s rule, AlCl3 is more covalent in nature.
Is AlCl3 ionic?
In the solid state it adopts an ‘ ionic lattice’ structure with octahedral coordination for the Al3+ ions but in the liquid and gas phases it exists as a covalent compound, either as AlCl3 or as a dimer Al2Cl6. We can rationalize this by considering the polarizing effect of the aluminium cation on the chloride anions.
Is Aluminium fluoride covalent or ionic?
Aluminium fluoride is ionic while AlCl3 is covalent.
Is aluminum and chlorine a covalent bond?
Ernest Z. Aluminum and chlorine form covalent bonds , not ionic bonds.
