Classification and Naming of Inorganic Compounds

Classification: Inorganic compounds can be classified into several categories based on their chemical composition and properties. Some common categories include oxides, hydroxides, salts, and acids.

Naming of Compounds: Inorganic compounds are named using specific rules based on the elements present and their oxidation states. The names often reflect the composition of the compounds.

1. Fe: - Classification: Iron (Fe) is a transition metal. - Naming: When it forms compounds, it can have different oxidation states. For example, FeO is iron(II) oxide, and Fe2O3 is iron(III) oxide.

2. S: - Classification: Sulfur (S) is a non-metal. - Naming: Sulfur can form various compounds, such as sulfur dioxide (SO2) and sulfur trioxide (SO3).

3. Cr: - Classification: Chromium (Cr) is a transition metal. - Naming: Similar to iron, chromium can have different oxidation states. For example, Cr2O3 is chromium(III) oxide.

4. P: - Classification: Phosphorus (P) is a non-metal. - Naming: Phosphorus forms compounds such as phosphoric acid (H3PO4) and phosphorus pentoxide (P2O5).

5. FeO: - Naming: FeO is iron(II) oxide.

6. Cr2O3: - Naming: Cr2O3 is chromium(III) oxide.

7. Fe(OH)3: - Naming: Fe(OH)3 is iron(III) hydroxide.

8. Cu(OH)2: - Naming: Cu(OH)2 is copper(II) hydroxide.

9. Na2Cr2O7: - Naming: Na2Cr2O7 is sodium dichromate.

10. HNO3: - Naming: HNO3 is nitric acid.

11. Co2: - Naming: Co2 is cobalt(II) oxide.

12. NaHCO3: - Naming: NaHCO3 is sodium bicarbonate, also known as baking soda.
