Answer

Answer:

  1. Sodium sulfide
  2. Aluminum oxide
  3. Sodium chloride
  4. Potassium iodide
  5. Zinc bromide
  6. $AlCl_{3}$
  7. $ZnO$
  8. $BaBr_{2}$
  9. $Li_{3}N$
  10. $K_{2}S$

Explanation:

Step1: Identify cation and anion

For naming compounds, identify metal (cation) and non - metal (anion). For formula writing, know the charges of ions.

Step2: Name ionic compounds

Name the cation first, then the anion with its ending changed to -ide. E.g., for $Na_2S$, sodium is the cation and sulfur becomes sulfide.

Step3: Write chemical formulas

Use the criss - cross method. For aluminum chloride, aluminum ($Al^{3 + }$) and chloride ($Cl^{-}$), so the formula is $AlCl_{3}$.
