Atoms: The fundamental building blocks of matter, composed of protons, neutrons, and electrons.
Elements: Pure substances consisting of only one type of atom.
Periodic Table: A systematic arrangement of elements based on their atomic number and chemical properties.
Chemical Bonding: The forces that hold atoms together to form molecules and compounds.
Chemical Reactions: Processes that involve the rearrangement of atoms and molecules.
Stoichiometry: The study of the quantitative relationships between reactants and products in chemical reactions.
States of Matter: Solids, liquids, and gases, each with unique properties.
Thermodynamics: The study of energy transformations in chemical systems.
