IB Diploma · SL/HL
Chemistry organised around two questions: how is matter built (Structure) and how does it change (Reactivity)? You will model atoms and bonds, then explore the energy, speed, extent and mechanisms of chemical reactions.
Lesson 1 is free to try. The other 7 lessons in Chemistry and its exam practice are for schools on RudimentaryLabs.
How atoms are built, where their electrons live, and how chemists count particles.
How atoms hold together, and how an element's position predicts its properties.
What drives reactions energetically, and what controls how fast they go.
How far reactions go, and how acids and bases swap protons.
