Chemistry

Course summary

Structure and Reactivity are the two overarching themes within IB. An outline of the topics taught within the two themes are shown below: STRUCTURE 1. Models of the particulate nature of matter • Introduction to the particulate nature of matter • The nuclear atom • Electron configurations • Counting particles by mass (the mole) • Ideal gases 2. Models of bonding and structure • The ionic model Structure • The covalent model • The metallic model • From models to materials 3. Classification of matter • The periodic table: Classification of elements • Functional groups: Classification of organic compounds REACTIVITY 1. What drives chemical reactions? • Measuring enthalpy change Reactivity • Energy cycles in reactions • Energy from fuels Reactivity • Entropy and spontaneity (Additional higher level) 2. How much, how fast and how far? • How much? The amount of chemical change • How fast? The rate of chemical change • How far? The extent of chemical change 3. What are the mechanisms of chemical change? • Proton transfer reactions Reactivity • Electron transfer reactions • Electron sharing reactions • Electron-pair sharing reactions
