Chemical Compounds - Set I

Introduction to Chemical Compounds

Chemical compounds are substances formed by two or more elements that are chemically bonded together. These compounds have unique properties different from the elements that form them.

Types of Chemical Compounds

1. Ionic Compounds: Formed by the attraction between positively and negatively charged ions. Example: Sodium chloride (NaCl)
2. Covalent Compounds: Formed by the sharing of electrons between atoms. Example: Water (H₂O)
3. Organic Compounds: Contain carbon and are often associated with living organisms. Example: Ethanol (C₂H₅OH)
4. Inorganic Compounds: Do not contain carbon. Example: Sodium chloride (NaCl)

Naming Chemical Compounds

Chemical compounds are named using specific rules and nomenclature. For example, ionic compounds are named by writing the name of the cation followed by the name of the anion.

Properties of Chemical Compounds

The properties of chemical compounds depend on the types of bonds and the arrangement of atoms within the compound. These properties include melting point, boiling point, solubility, conductivity, and more.

Study Tips

• Understand the difference between ionic and covalent compounds.
• Practice naming chemical compounds using nomenclature rules.
• Review the properties of different types of chemical compounds and how they are related to their bonding and structure.
• Use visual aids such as molecular models or diagrams to understand the arrangement of atoms in compounds.
