This bundle is the first in a series covering the OCR AS Chemistry specification and relates to the following sections: Module 2 – Foundations in chemistry / Part 1 – Atoms and reactions 2.1.1 – Atomic structure and isotopes and 2.1.2 – Formulae and equations Content covered The Changing Atom • How Science Works - HSW7 - The changing accepted models of atomic structure over time. • The contributions of five scientists to the development of the theory of atomic structure. Atomic structure • Protons, neutrons and electrons – mass and relative charge • Atomic number and mass number • Isotopes • Key definitions Atomic masses • Relative masses - comparison of masses to carbon-12 • Calculating relative atomic mass from the masses and abundances of the isotopes • Mass spectrometry and its use in the above • Calculating relative molecular and relative formula masses from formulae • Key definitions of relative atomic mass and relative isotopic mass Formulae and Equations • Formulae of ions • Predicting ionic charges from the Periodic Table • Writing the formulae of ionic compounds and elements • Writing and balancing equations • Common types of reaction and their equations Links Next lesson – free resource: Topic 5 – Amount of substance and the mole https://www.tes.com/teaching-resource/amount-and-moles-ocr-as-chemistry-12190652 Next bundle - Moles, masses, concentrations, gas volumes and reactions (covers whole of OCR section 2.1.3) https://www.tes.com/teaching-resource/moles-masses-concentrations-gas-volumes-and-reactions-12404451
