Let's solve this Nomenclature Worksheet 5: Ionic Compounds Summary step by step. We'll go through each compound, naming them correctly (for the left side) and writing formulas (for the right side), using proper ionic compound nomenclature rules.

🔹 Part A: Name the following compounds

We identify the cation and anion, then apply naming rules:
- For metals with fixed charges (e.g., Na⁺, Ca²⁺): just name the metal + anion.
- For metals with variable charges (e.g., Fe, Cu, Cr): use Roman numerals to indicate charge.
- Polyatomic ions have specific names (e.g., NO₃⁻ = nitrate, CO₃²⁻ = carbonate, etc.).

📌 Key Concepts Used:

- Fixed charge metals: Group 1, 2, and some transition metals like Ag⁺, Zn²⁺, Cd²⁺.
- Variable charge metals: Use Roman numerals (e.g., Fe²⁺ = iron(II), Fe³⁺ = iron(III)).
- Polyatomic ions: Memorize common ones (e.g., NO₃⁻, SO₄²⁻, CO₃²⁻, OH⁻, NH₄⁺, etc.).
- Mercury(I): Always exists as Hg₂²⁺, so it's written as Hg₂(NO₃)₂.
- Charge balancing: Total positive charge = total negative charge.
