The Periodic Table point1: Elements in the same group have the same number of electrons in the outer shell (this correspond to their group number) entrancei.com H Hg Au Pt Xe I Ag Kr Br Zn Cu Ni Fe Ca K Ar Cl S P Si Al Mg Na Ne F O N C B Be Li He E.g. all group 1 metals have __ electron in their outer shell These elements have __ electrons in their outer shell These elements have __ electrons in their outer shells 3. Periodic table Horizontal rows are called PERIODS entrancei.com The periodic table arranges all the elements in groups according to their properties. Vertical columns are called GROUPS 4. The Periodic Table Point.. 2: As you move down through the periods an extra electron shell is added: entrancei.com H Hg Au Pt Xe I Ag Kr Br Zn Cu Ni Fe Ca K Ar Cl S P Si Al Mg Na Ne F O N C B Be Li He E.g. Lithium has 3 electron in the configuration 2,1 Potassium has 19 electrons in the configuration __,__,__ Sodium has 11 electrons in the configuration 2,8,1 5. The Periodic Table point 3: Most of the elements are metals: entrancei.com H Hg Au Pt Xe I Ag Kr Br Zn Cu Ni Fe Ca K Ar Cl S P Si Al Mg Na Ne F O N C B Be Li He These elements are metals This line divides metals from non-metals These elements are non-metals 8. Group 0 – The Noble gases entrancei.com Rn Xe Kr Ar Ne He 10. Group 1 – The alkali metals entrancei.com Fr Cs Rb K Na Li 11. Group 7 – The halogens entrancei.com At I Br Cl F 12. Group 7 – The Halogens Some facts… 1) Reactivity DECREASES as you go down the group (This is because the electrons are further away from the nucleus and so any extra electrons aren’t attracted as much). 2) They exist as diatomic molecules (so that they both have a full outer shell): 3) Because of this fluorine and chlorine are liquid at room temperature and bromine is a gas entrancei.com Decreasing reactivity Cl Cl 13.
