Solution Steps

Step 1: Identify the Chemical Formula Components
  • The chemical formula \(\mathrm{Na}_{2} \mathrm{SO}_{4}\) represents a compound consisting of sodium (Na), sulfur (S), and oxygen (O) atoms.
Step 2: Count the Atoms in the Formula
  • The subscript numbers in the formula indicate the number of each type of atom present:
    • \(\mathrm{Na}_{2}\) indicates there are 2 sodium atoms.
    • \(\mathrm{SO}_{4}\) indicates there is 1 sulfur atom and 4 oxygen atoms.
Step 3: Verify the Atom Count
  • Confirm that the total number of each type of atom matches the description:
    • 2 sodium atoms, 1 sulfur atom, and 4 oxygen atoms are present in the compound, as described.

Final Answer

\(\boxed{2 \text{ sodium atoms}, 1 \text{ sulfur atom}, 4 \text{ oxygen atoms}}\)
