1.1 The Particulate Nature of Matter

Essential Idea: Physical and Chemical Properties depend on the ways in which different atoms combine

Understanding 1: Atoms of different elements combine in fixed ratios to form compounds, which have different properties from their component elements

In order to understand how to approach this area you must access the Prior Learning Section as how we balance chemical equations and how we make up compounds from different elements is discussed in detail in these sections - you should aim to complete two worksheets in the prior learning area (here) entitled:

• Finding Formula
• Balancing Equations
