PRINCIPLES OF CHEMISTRY

a. States of matter

1.1 - 1.2 The three states

Understand the three states of matter in terms of the arrangement, movement and energy of the particles

1.3 A particular problem

understand and explain dilution and diffusion

1.4 - 1.7 Solubility curves

solutions, dissolving and solubility

b. Elements, compounds and mixtures

1.8 Element or compound?

Classify substances as element or compound

1.10 Separation techniques

Explore a range of physical techniques for separating substances

1.10 - 1.13 Chromatography

Understand how to make and analyse chromatograms

c. Atomic Structure

1.14 Atoms and molecules

Know what is meant by the terms atom and molecule

1.15 Subatomic particles

know the structure of an atom in terms of subatomic particles

1.16 Isotopes

know what is meant by the terms atomic number, mass number, isotopes and relative atomic mass (Ar)

1.17 Relative atomic mass

be able to calculate the relative atomic mass of an element (Ar) from isotopic abundances

d. The Periodic Table

1.18 Organising elements

understand how elements are arranged in the Periodic Table

1.19 Electron configurations

understand how to deduce the electronic configurations of the first 20 elements from their positions in the Periodic Table
