What is the correct name for the ionic compound formed between magnesium and sulfur atoms?

• A. Magnesium sulfide
• B. Magnesium sulfur
• C. Magnesium sulfate
• D. Magnesium(II) sulfuride

Answer: (A)

Verified step by step guidance

1. Identify the elements involved: magnesium (Mg) and sulfur (S).
2. Determine the charges of the ions each element forms: magnesium typically forms a +2 charge (Mg^{2+}), and sulfur typically forms a -2 charge (S^{2-}).
3. Combine the ions in a ratio that results in a neutral compound. Since both charges are equal and opposite (+2 and -2), they combine in a 1:1 ratio to form MgS.
4. Name the compound by stating the metal first (magnesium) followed by the nonmetal with its ending changed to '-ide' (sulfide).
5. Confirm that the correct name for the compound MgS is 'magnesium sulfide', which matches the naming conventions for ionic compounds.
