Step-by-step solution for: 11 - Ionic Compounds Nomenclature Worksheet - Date: - Studocu
Absolutely! Let’s solve this Naming Binary Ionic Compounds worksheet step by step. This is a foundational chemistry skill involving writing formulas from names (Part A) and naming compounds from formulas (Part B).

## 🔬 Key Concepts:
- Binary ionic compounds consist of two elements: one metal (cation, positive ion) and one nonmetal (anion, negative ion).
- The total charge must be neutral (sum of charges = 0).
- Use criss-cross method or lowest whole-number ratios to balance charges.
- For transition metals with variable charges (like Fe, Cu, Cr, Mn), the Roman numeral indicates the charge of the metal ion.
---
# ✔ Part A: Write the formula for each compound
We’ll use the criss-cross method: write the charges, swap them as subscripts (simplify if needed).

## 🧠 Final Tips:
- Always check if the metal has variable charge (transition metals like Fe, Cu, Cr, Mn, Sn, Pb). If yes, you need a Roman numeral.
- Group 1, 2, and Al don’t need Roman numerals — their charges are fixed.
- Nonmetals in binary ionic compounds get the suffix “-ide”.
- Balance charges using lowest whole number ratios.
