SOMEONE ASKED ๐
Predict the chemical formula of the ionic compound formed between the following pairs of elements?
HERE THE ANSWERS ๐
-
A) AlF3
B) K2S
C)Y2O3
D) Mg3N2
I figured out this from the number of valence electrons. You see the non metals take electrons and the metals take them.
I found Y now. In the third group.

4 is the only one i would question. Think of SO3 and SO4, the ratio isn’t constant, so I would go with D as the answer.
