Summary Naming simple compounds

Naming Simple Compounds notes

🧪 1. Types of Simple Compounds
Compound Type Elements Involved Example
Ionic Compounds Metal + Non-metal NaCl, MgO
Covalent (Molecular) Non-metal + Non-metal CO₂, H₂O
HCl,
Acids (basic) Hydrogen + Non-metal (or ion)
H₂SO₄


⚡ 2. Naming Ionic Compounds
🧱 Basic Rules:

1. Name the metal first (positive ion).
2. Name the non-metal second, change the ending to “-ide.”

✅ Examples:

 NaCl → Sodium chloride
 MgO → Magnesium oxide
 CaBr₂ → Calcium bromide

🧠 With Transition Metals:

Some metals have more than one possible charge (like Fe²⁺ or Fe³⁺). Use Roman
numerals to show the charge.

Examples:

 FeCl₂ → Iron(II) chloride
 FeCl₃ → Iron(III) chloride
 Cu₂O → Copper(I) oxide
 CuO → Copper(II) oxide




🧬 3. Naming Covalent (Molecular) Compounds
🧱 Basic Rules:

1. Name the first non-metal (prefix if more than 1).
2. Name the second non-metal with prefix and “-ide.”
