Which statement best predicts and explains the product of a single displacement reaction when the cation (A) with an oxidation number of +2 and an anion (B) with the oxidation number of -3 react and form a compound? A+2B-3 is the predicted formula when each metal cation has a charge of +2 and each non metal has a charge of -3.

B2A3 is the final formula for the metal anion bonding to the non-metal cation in a 2:3 ratio.

A3B2 is the predicted formula with an overall charge of the compound being zero and each atom has 8 valence electrons in their outermost electron shell.

A3B2 is the predicted formula is made when each metal cation gains three electrons from the anion while each nonmetal loses 2 electrons to each of the cations.
