Periodic Table L.O.’s: 1. recap the structure of atoms 2. recognise Groups and Periods in the Periodic Table   Discuss, copy and label the structure of this Helium atom

All ATOMS have PROTONS, NEUTRONS AND ELECTRONS All ATOMS have PROTONS, NEUTRONS AND ELECTRONS. The periodic table tells us how many of each an atom has.

Group 7 halogens Group 8 Noble gases Very reactive Disinfectants-kill bacteria bleaching Group 8 Noble gases

Group 1(Alkali metals) reaction with water demo To discuss, and then add to your description on the periodic table Why are the group 1 metals kept in oil? Why colour did the universal indicator turn and what does this tell you about the solution formed? What explosive gas do you think is given off when an alkali metal reacts with water? Hint: think of the POP test
