Year 10 Science Course 2 Term 1: CHEMICAL SCIENCES
Chemistry - to be delivered in Term 1 (2nd February to 7th April: 10 teaching weeks)
Text: Oxford Science 10
Year 10 Chemical Sciences Content Descriptions
The atomic structure and properties of elements are used to organise them in the Periodic Table (ACSSU186)
• recognising that elements in the same group of the periodic table have similar properties
• describing the structure of atoms in terms of electron shells
• explaining how the electronic structure of an atom determines its position in the periodic table and its
properties
• investigating the chemical activity of metals
Different types of chemical reactions are used to produce a range of products and can occur at different rates
(ACSSU187)
• investigating how chemistry can be used to produce a range of useful substances such as fuels, metals and
pharmaceuticals
• predicting the products of different types of simple chemical reactions
• using word or symbol equations to represent chemical reactions
• investigating the effect of a range of factors, such as temperature and catalysts, on the rate of chemical
reactions

Define atomic and mass number and
calculate the number or protons, neutrons
and electrons.
Students must know the first 20 element

Pages 78-83 of textbook (Chapters 3.5,
3.6 & 3.7))
Explain the octet rule- All atoms want 8
electrons in the outer (valence) shell.
This achieves a noble gas configuration.
Formation of ions
This can be done by losing or gaining or
due to losing or
sharing electrons.
