Chemistry flashcards and quizzes

Chemistry flashcards are ideal for definitions, ion formulae, tests and reaction conditions, and practice quizzes help with the calculations and the reasoning about bonding and reactions that make up much of the exam.

Pick a topic to open a ready-made set request: choose your level and counts, then generate. For exam revision, narrow it to your unit or paste your class notes.

Levels

What does chemistry cover at each level?

School (about ages 11–16)

Atomic structure, the periodic table, bonding, quantitative chemistry, reactions, energy changes, rates and organic basics.

Pre-university (A-Level, IB, AP)

Deeper physical, inorganic and organic chemistry: thermodynamics, kinetics, equilibria, mechanisms and spectroscopy.

University

Physical, inorganic and organic chemistry as separate disciplines, with quantum and analytical chemistry.

Courses differ by country and exam board, so check your own specification. Our exam board guides cover 23 countries and curricula.

Exam boards

Exam board guides for chemistry

Chemistry is examined by 37 of the boards and qualifications we cover. Each guide explains grading, exam dates and what to know, with sets matched to that board.

Revision

How should you revise chemistry?

Card the things you must just know

Ion formulae, state symbols, test results and reaction conditions are pure recall. They are perfect flashcards, and knowing them instantly frees up time for calculations.

Practise calculations, don't just read them

Moles, concentrations and yields only stick with practice. Use quiz questions, write out every step, and include units.

Link structure to properties

Most "explain" questions want you to connect structure and bonding to a property, like a high melting point. Make cards that ask why.

Balance an equation a day

Balancing equations is a skill that fades quickly. A few each day keeps it automatic.

Watch out

What are the most common chemistry mistakes?

  • Mistake: Solid ionic compounds conduct electricity.

    Correct: Ionic compounds conduct only when melted or dissolved, because then the ions are free to move.

  • Mistake: Breaking bonds releases energy.

    Correct: Breaking bonds always takes in energy and making bonds releases it. A reaction is exothermic when more energy is released making bonds than is taken in breaking them.

  • Mistake: A catalyst gets used up in the reaction.

    Correct: A catalyst speeds up a reaction by providing a route with a lower activation energy, and is not used up.

  • Mistake: All atoms of an element have the same mass.

    Correct: Isotopes of an element have the same number of protons but different numbers of neutrons, so different masses.

Examples

Sample chemistry flashcards

One idea per card, a clear question, a short answer. This is the style every generated set follows.

Chemistry

What is the test for hydrogen gas?

Back

Hold a lit splint at the mouth of the test tube: hydrogen burns with a squeaky pop.

Chemistry

What is the formula of the sulfate ion?

Back

SO₄²⁻

Chemistry

What is Avogadro's constant?

Back

6.02 × 10²³: the number of particles in one mole of a substance.

FAQ

Chemistry: questions

How do I get better at chemistry calculations?

Learn the few core equations as flashcards, then practise mixed calculation questions with full working and units. Most errors come from skipped steps, not from not knowing the equation.

Do I need to memorise the periodic table?

Usually not: you get a copy in the exam. Learn how it is organised, the trends in groups and periods, and the properties of the main groups.

What chemistry topics are hardest?

Students often find moles and quantitative chemistry, electrolysis, and organic reaction mechanisms the hardest. Short, regular practice beats long sessions for all three.
