1. How has the periodic table developed over time?
All pupils will be able to (Baseline): Describe how elements in the periodic table are organised by their atomic number and reactivity.
Most pupils will be able to (Further): Explain how the position of an element in the periodic table is related to its atomic number and some of the steps in the development of the periodic table.
Some pupils will be able to (Challenge): Predict possible reactions and probable reactivity of elements from their positions in the periodic table.

3. The Periodic Table – A Bit of History
The modern periodic table was laid out by a man called Dimitri Mendeleev.
The periodic table is essentially a map of all of the known elements in the universe.
It does not look much at first glance, but is THE most important reference point for discovering what the universe is made of.

7. John Newlands, 1865
Law of Octaves – properties repeat every 8th element

8. Dimitri Mendeleev, 1869 - Left gaps for undiscovered elements
- Swapped order around (e.g. Te, I) to fit properties

9. Suggest how Mendeleev may have been able to predict the properties of Rubidium?
