Chapter 1: Atomic Theory and Structure
- Understanding Atoms
- An atom consists of protons, neutrons, and electrons.
- Atomic mass and atomic number are key identifiers of the element.
Chapter 2: Chemical Bonding
- Types of Bonds
- Ionic bonds form when electrons are transferred from one atom to another.
- Covalent bonds involve sharing electrons between atoms.
Chapter 3: States of Matter
- Phases of Matter
- Solids, liquids, and gases exhibit different properties based on the arrangement of their particles.
- Phase changes involve energy changes and can be represented by phase diagrams.
Chapter 4: Solutions
- Properties of Solutions
- Solutions are homogeneous mixtures of solute(s) and solvents.
- Key concepts include molarity and molality, which measure concentration.
Chapter 5: Chemical Reactions
- Types of Reactions
- Understand redox reactions, synthesis, and decomposition reactions.
