GCSE Chemistry

Key Learning points:

• An introduction to what an atom is
• Understanding the concept of sub-atomic particles
• Mass Number
• Atomic Number.

Learning objectives:

• Describe the steps involved in the development of the periodic table.
• Understand that elements in the periodic table are arranged in order of atomic no. 
• Understand that elements in the same group have similar chemical properties.

Students should be able to:

• explain how properties of the elements in Group 1 depend on the outer shell of electrons of the atoms.
• predict properties from given trends down the group.

Students should be able to:

• Explain how properties of the elements in Group 7 depend on the outer shell of electrons of the atoms
• Predict properties from given trends down the group.
