Demonstrate that you understand how the trends across periods in the periodic table affect chemical and physics properties of elements by:

$$ Explaining the trends in period $3$ of the periodic table.

$$ Using the periodic table to predict properties of elements in period $3.$

$$ Explaining ionisation energy across period $3.$

$$ Predicting electron configuration from ionisation energies.

Include diagrams and graphs to support your commentary where appropriate. It is also recommended that you use a wide variety of example reactions, including balanced symbol equations to illustrate your ideas.
