Question

current attempt in progress
does the fact that two elements combine in a one - to - one atomic ratio mean that the charges on their ions are both 1? explain
, because the charges on the ions in one - to - one compounds

Explanation:

In ionic compounds, the formula is determined by the requirement that the overall charge be zero. For a one - to - one atomic ratio compound \(AB\), the charges on the ions \(A^{x +}\) and \(B^{y-}\) must satisfy \(x=y\). But the value of \(x\) (or \(y\)) is not necessarily \(1\). For example, in \(CaO\), \(Ca^{2 +}\) and \(O^{2-}\) combine in a one - to - one ratio.

Answer:

No, because the charges on the ions are equal in magnitude (but not necessarily \(1\)) in one - to - one compounds.
