It also outlines the periodic table’s organization by atomic number, groups and periods, plus development influenced by Mendeleev. Key properties of metals and nonmetals, group trends, and reactions with oxygen, water and chlorine are summarized.","CHEMISTRY KNOWLEDGE ORGANISERS  \nbetter hope – brighter future  \n| Mixtures | Two or more elements or compounds not chemically combined together | Can be separated by physical processes. |\n| --- | --- | --- |\n\n\n| Method | Description | Example |\n| --- | --- | --- |\n| Filtration | Separating an insoluble solid from a liquid | To get sand from a mixture of sand, salt and water. |\n| Crystallisation | To separate a solid from a solution | To obtain pure crystals of sodium chloride from salt water. |\n| Simple distillation | To separate a solvent from a solution | To get pure water from salt water. |\n| Fractional distillation | Separating a mixture of liquids each with different boiling points | To separate the different compounds in crude oil. |\n| Chromatography | Separating substances that move at different rates through a medium | To separate out the dyes in food colouring. |\n\n| Chemical equations |  | Show chemical reactions-need reactant(s) and product(s) energy always involves and energy change | Law of conservation of mass states the total mass of products = the total mass of reactants. |  |\n| --- | --- | --- | --- | --- |\n|  |  |  |  |  |\n| Word\u003Cbr>equations | Uses words to show reaction\u003Cbr>reactants 􀃆 products\u003Cbr>magnesium + oxygen 􀃆 magnesium oxide |  |  | Does not show what is happening to the atoms or the number of atoms. |\n| Symbol equations | Uses symbols to show reaction\u003Cbr>reactants 􀃆 products 2Mg + O2 􀃆 2MgO |  |  | Shows the number of atoms and molecules in the reaction, these need to be balanced. |\n\n\n| Isotopes | Atoms of the same element with the same number of protons and different numbers of neutrons | 35Cl (75%) and 37Cl (25%)\u003Cbr>Relative abundance =(% isotope 1 x mass isotope 1) + (% isotope\u003Cbr>2 x mass isotope 2) ÷ 100\u003Cbr>e.g. (25 x 37) + (75x 35) ÷ 100 = 35.5 |\n| --- | --- | --- |\n\nRelative atomic mass  \nbetter hope – brighter future  \nAQA GCSE Atomic structure and periodic table part 2  \nMetals and non metals  \nThe Periodic table  \nGroup 0  \nTransition metals (Chemistry only)  \nH  \nLi  \nNa  \nK  \nRb  \nCs  \nFr  \nBe  \nSc  \nTi  \nMg  \nV  \nCr  \nMn  \nFe  \nCo  \nNi  \nCu  \nZn  \nGa  \n\n|  |  |  |  |\n| --- | --- | --- | --- |\n| \u003Cbr>Si |  P | S | Cl |\n| Ge | \u003Cbr>As |  Se | Br |\n| Sn | Sb | \u003Cbr>Te | I |\n| Pb | Bi | Po | At  |\n\nCa  \nKr  \nY  \nZr  \nNb  \nMo  \nTc  \nRu  \nPd  \nAg  \nCd  \nIn  \nSr  \nRh  \nBa  \nHf  \nTa  \nW  \nRe  \nOs  \nIr  \nAu  \nHg  \nTl  \nLa  \nPt  \nRa  \nRf  \nDb  \nSg  \nBh  \nHs  \nMt  \n?  \n?  \nAc  \n?  \nAl  \nN  \nO  \nF  \nNe  \nAr  \nRn  \nXe  \nHe  \nB  \nC  \n|  | Unreactive,\u003Cbr>do not form\u003Cbr>molecules\u003Cbr>Boiling\u003Cbr>points\u003Cbr>increase\u003Cbr>down the\u003Cbr>group | This is due\u003Cbr>to having\u003Cbr>full outer\u003Cbr>shells of\u003Cbr>electrons.\u003Cbr>Increasing\u003Cbr>atomic\u003Cbr>number. |\n| --- | --- | --- |\n\n| Elements arranged in order of atomic number | Elements with similar properties are in columns called groups | Elements in the same group have the same number of outer shell electrons and elements in the same period (row) have the same number of electron shells. |\n| --- | --- | --- |\n\n|  | Elements arranged in order of atomic weight | Early periodic tables were incomplete, some elements were placed in inappropriate groups if the strict order atomic weights was followed. |\n| --- | --- | --- |\n|  | Left gaps for elements that hadn’t been discovered yet | Elements with properties predicted by Mendeleev were discovered and filled in the gaps.
