This document summarises all you need to know about module 2 of OCR Chemistry A syllabus, with chapters of periodicity and reactivity trends included as well, so that you don't ever need to go to your textbook again!

Topic 1 - Atoms, Electrons and Periodicity This topic covers 1.1.1 Atoms, 1.2.1 Electron Structure and 1.3.1 Periodicity (except melting and boiling point trends)

Practice Test for periodicity section of A level Chemistry with answers.

coincise notes on module 3 content including : halogens, group 2, periodicity, ionisation energy chemical equations for representing ionisation energy

detailed notes on content in module 2 including: electronic astructure and configuration, bonding and structure, types of intermolecular forces and shapes of covalent molecules diagrams to aid learning

Chemistry class notes about Topic 2.1 Atoms and Reactions. Nice and clear.

OCR alevel in-depth physical chemistry notes for paper 1 and paper 3.

This is the first theory module of AS Level Chemistry by OCR.

Notes are summarise and are less overwhelming than revising from text books.
