Chemistry Flashcards

Build a solid foundation in chemistry by mastering the periodic table with this comprehensive flashcard deck. Each card covers an element's name, symbol, atomic number, group, period, and key physical and chemical properties. Understanding the periodic table is the single most important skill in chemistry — it unlocks the logic behind every reaction, bond, and property you will study. This deck covers the first 36 elements in depth, all noble gases, alkali metals, alkaline earth metals, halogens, and transition metals frequently tested in AP Chemistry, GCSE, A-Level, and university chemistry courses. Also includes periodic trends such as electronegativity, ionization energy, and atomic radius.

Understand why and how atoms bond together with this essential chemical bonding flashcard deck. Chemical bonding is the foundation of molecular chemistry — mastering it explains the properties of every substance you encounter, from water to DNA to metals. This deck covers ionic bonding, covalent bonding (polar and nonpolar), metallic bonding, Lewis dot structures, electronegativity and bond polarity, VSEPR theory and molecular geometry, hybridization, and intermolecular forces including hydrogen bonding, dipole-dipole interactions, and London dispersion forces. Essential for AP Chemistry, GCSE, A-Level, and university general chemistry courses.

Master one of chemistry's most important topics with this comprehensive acids, bases, and pH flashcard deck. Understanding acid-base chemistry is essential for biology, medicine, environmental science, and industrial chemistry — and it is one of the most heavily tested topics in AP Chemistry, A-Level, GCSE, and university general chemistry courses. This deck covers the three major definitions of acids and bases (Arrhenius, Brønsted-Lowry, and Lewis), the pH scale, strong and weak acids and bases, neutralization reactions, buffer solutions, titrations, Ka and Kb values, and common acid-base indicators. Includes worked examples of pH calculations.

Build your organic chemistry foundation with this essential flashcard deck covering the key concepts, functional groups, and reaction types you need to know. Organic chemistry studies carbon-containing compounds and is fundamental to biology, medicine, materials science, and the pharmaceutical industry. This deck covers IUPAC nomenclature, hydrocarbons (alkanes, alkenes, alkynes), aromatic compounds, and the major functional groups including alcohols, ethers, aldehydes, ketones, carboxylic acids, esters, amines, and amides — along with their properties and characteristic reactions. Essential for AP Chemistry, A-Level, and first-year university organic chemistry courses.

Master chemical reactions and stoichiometry — the mathematical heart of chemistry — with this comprehensive flashcard deck. Stoichiometry allows chemists to predict exactly how much of each substance is needed or produced in a reaction, making it essential for every branch of chemistry, from laboratory work to industrial manufacturing. This deck covers the five main types of chemical reactions, how to balance chemical equations, mole calculations, molar mass, limiting and excess reagents, theoretical and percent yield, concentration calculations, and gas stoichiometry. Essential for AP Chemistry, GCSE, A-Level, and university general chemistry.

Understand the energy changes that drive chemical reactions with this comprehensive thermodynamics and thermochemistry flashcard deck. Thermodynamics answers one of chemistry's most fundamental questions: why do reactions occur spontaneously in one direction? This deck covers the laws of thermodynamics, heat and work, enthalpy (ΔH), entropy (ΔS), Gibbs free energy (ΔG), Hess's law, standard enthalpies of formation, calorimetry calculations, specific heat capacity, and bond enthalpy calculations. Essential for AP Chemistry, A-Level Chemistry, IB Chemistry, and university general and physical chemistry courses.
