In neutral sodium bromide (NaBr), what is the ratio of sodium ions to bromide ions present in the compound?

• A. 2:3
• B. 2:1
• C. 1:1
• D. 3:2

Answer: (C)

Verified step by step guidance

1. Identify the chemical formula of the compound given, which is sodium bromide (NaBr).
2. Recognize that sodium bromide is an ionic compound composed of sodium ions (Na\textsuperscript{+}) and bromide ions (Br\textsuperscript{-}).
3. Understand that the formula NaBr indicates the ratio of sodium ions to bromide ions in the compound.
4. Since there is one sodium ion for every bromide ion in the formula, the ratio of sodium ions to bromide ions is 1:1.
5. Conclude that the ratio 1:1 means equal numbers of sodium and bromide ions are present in neutral sodium bromide.
