Atoms and the periodic table

Define an element and learn how different elements are represented by chemical symbols.

Elements

Define a compound, write compound formulae and name compounds based on the atoms they contain.

Compounds

Understand the difference between physical and chemical changes and write equations using word and symbol equations.

Chemical reactions

Describe what is meant by 'conservation of mass' and apply this to chemical and physical changes.

Conservation of mass

Understand that elements have different properties and how the periodic table has been developed over time according to our knowledge of these properties.

Development of the Periodic Table

Describe the common properties of metals and non-metals and how different uses relate to their properties.

Metals and non-metals

Describe the physical and chemical properties of Group 1 metals and trends in their reactions with oxygen and water.

Group 1

Describe the trends in reactivity of Group 7 elements and how they react with different Group 7 elements and elements from other groups.
