Atomic structure, masses, formulae and equations OCR AS Chemistry

This bundle is ideal for classroom or home learning and covers the whole of the OCR A level chemistry specification sections 2.1.1 and 2.1.2.
Each topic includes a fully interactive PowerPoint including starter, group activities, questions and plenary along with a worksheet and a lesson plan. Answers to all exercises are provided. Three of the resources include a PowerPoint quiz.

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
