Step 1:I'll solve this problem step by step, following the specified LaTeX and formatting guidelines:
Step 2:: Understand the Basic Principles of Chemical Formulas
Chemical formulas are written to represent the simplest whole-number ratio of atoms in a compound. To determine the correct formula, we need to consider the ionic charges of magnesium and sulfur.
Step 3:: Determine the Ionic Charges
- Magnesium (Mg) is a Group 2 metal that typically forms $$Mg^{2+}$$ ions
- Sulfur (S) is a Group 16 nonmetal that typically forms S^{2 -} ions
Step 4:: Balance the Charges
This means the simplest ratio is 1:1, resulting in the formula $$MgS
To create a neutral compound, we need to balance the positive and negative charges:
Step 5:: Explain Why Not Mg_{2}S_{2}
- Two $$S^{2-}$$ ions
- Two Mg^{2 +} ions This would not balance the charges and is unnecessarily complex.
Final Answer
The chemical formula for magnesium sulfide is MgS because it represents the simplest whole-number ratio that neutralizes the ionic charges of magnesium and sulfur.
