Question

the ratio of the elements in a binary ionic compound are based on the elements ________. a oxidation number b mass number c total number of neutrons if combining cation a with a +3 charge and anion x with a -3 charge, how would we write the compound? a ax

Explanation:

1. For the first question: Binary ionic compounds form when positive and negative charges balance. Oxidation number (or ionic charge) determines how many of each ion is needed to make a neutral compound. Mass number and neutron count do not affect ionic ratios.
2. For the second question: When a cation with +3 charge (A³⁺) and anion with -3 charge (X³⁻) combine, their charges cancel out in a 1:1 ratio, so the compound formula is AX.

Answer:

1. A. oxidation number
2. A. AX
