The atomic number of an element does not determine the ratio in which it combines with another element to form a compound. The ratio in which elements combine to form a compound is determined by the valency of the elements. The valency of an element is determined by the number of electrons in the outermost shell of its atoms.

In the case of Element A with atomic number 56, it is Barium (Ba) and it has a valency of 2.

Element B with atomic number 15 is Phosphorus (P) and it has a valency of 3 or 5 (depending on the type of compound it forms).

If we assume that the valency of Phosphorus in this compound is 3, then the chemical formula would be Ba3P2.

So, in this case, the value of y would be 2.

However, if we assume that the valency of Phosphorus in this compound is 5, then the chemical formula would be Ba5P2.

So, in this case, the value of y would still be 2.

Therefore
