📖 1. Elements and Compounds

🔑 Key Concepts & Definitions

• Element: A pure substance consisting of only one type of atom. It cannot be broken down into simpler substances by chemical means.
• Compound: A pure substance made from two or more elements chemically combined in fixed proportions. It has unique properties different from its constituent elements.
• Chemical formula: A notation that shows the types and numbers of atoms in a compound, such as H₂O for water. It provides a concise way to represent chemical composition.
• Difference between elements and compounds: Elements contain only one type of atom and cannot be broken down further by chemical means, whereas compounds consist of multiple types of atoms bonded together chemically, with a fixed ratio.
• Atomic structure basics relevant to elements and compounds: Elements are made of atoms with a specific number of protons, neutrons, and electrons. The arrangement of electrons determines how atoms bond to form compounds.
