Ionic formula from ion charges

A metal ion in a marine chemistry comparison has charge \(1+\), and the non-metal ion has charge \(1-\). Determine the simplest cation:anion ratio for a neutral ionic compound. Use the diagram labels first, then answer carefully. Enter the answer and choose the interpretation that matches the chemistry.

Worked practice: chemistry evidence and answer

Use the chemical evidence first, then enter the result and interpretation that match it.
