Activities

• recognise the three sub-atomic particles and their positions within the atom.

• be able to calculate the number of sub-atomic particles given the mass and atomic numbers¨ appreciate the existance of isotopes and their everyday uses.

• understand the relationship between the layout of the periodic table and the sub-atomic structure

• recognise that the electronic configuration gives rise to chemical activity

• recognise that the electronic structure determines the nature of the elements
