Aluminum Forms An Ionic Compound With An Element To Give The Formula Al2X3 Which Ion Below Could Be X class=

Sagot :

Answer:

[tex]S^{2-}[/tex]

Explanation:

Here, we want to know the possible ion with which aluminium forms the hypothetical compound

As we know, aluminium is a metallic compound and thus have a positive ion. The charge on this ion is +3

This is evident from the hypothetical compound

However, we can see that for a compund to be formed, we need an interchanging of ions and that would serve as the subscript

From the hypothetical compound, we can see that the subscript is 2

That automatically means that we need an ion with a -2 charge

Looking at the option, we can see this in S2-

This will serve as the correct choice for X
