Which 2 elements will form an ionic compound with a 3:2 ratio? Mg and Al
Na and N
Mg and S
Be and P
Li and Al

Mg and Al

Explanation:

The two elements that will form an ionic compound with a ratio 3:2 is Mg and Al.

Mg has a valency of 2

Al has a valency of 3

 To form an ionic bond, there is a transfer of electrons from the Mg to the Al.

This leaves a positive charge on the Mg and a negative charge on Al

When the valency is exchange, we would have:

                     Mg₃Al₂  

So the elements are Mg and Al
