Explanation:

Step1: Recall naming rules for ionic compounds

For binary ionic compounds, name the metal first followed by the non - metal with the non - metal ending in “ide”. For polyatomic ions, use their specific names.

Step2: Name Na₂S

Sodium is the metal and sulfur is the non - metal. The name is sodium sulfide.

Step3: Name Mg₃N₂

Magnesium is the metal and nitrogen is the non - metal. The name is magnesium nitride.

Step4: Name AlCl₃

Aluminum is the metal and chlorine is the non - metal. The name is aluminum chloride.

Step5: Name FeO

Iron has a + 2 oxidation state here, so it is iron (II) oxide.

Step6: Name CuBr₂

Copper has a + 2 oxidation state here, so it is copper (II) bromide.

Step7: Name K₃P

Potassium is the metal and phosphorus is the non - metal. The name is potassium phosphide.

Step8: Name HgNO₃

Mercury has a + 1 oxidation state here, so it is mercury (I) nitrate.

Step9: Name ZnCO₃

Zinc is the metal and carbonate is the polyatomic ion. The name is zinc carbonate.

Step10: Name NaClO₃

Sodium is the metal and chlorate is the polyatomic ion. The name is sodium chlorate.

Answer:

1. sodium sulfide (orange)

3. aluminum chloride (purple)
4. iron (II) oxide (pink)
5. copper (II) bromide (magenta)
6. potassium phosphide (green)
7. mercury (I) nitrate (orange)
8. zinc carbonate (purple)
9. sodium chlorate (green)
