C1 - Atoms & Elements

1. separating mixtures

   • filltration
     • FILTRATE
       • the liquid that passes through the filter paper
       • residue
         • a solid left in filter paper
       • separates an insoluble solid from a liquid
         • equipment
           • funnel filter paper conical flask
   • crystilisation
     • evaporation
     • separates a soluble solid from a liquid
       • equipment
         • evaporating basin heat
   • chromatography
     • separates inks and food clouring
   • distillation
     • separates two liquids with different boiling points
     • evaporation of one liquid happens in the round bottomed flask
       • the vapor condenses in the condenser and collects in the beaker
         • the other liquid dosent evaporate and stays in the round bottomed flask

2. structure o the atom

   • charge
     • proton-1+
     • electron-1-
   • mass
     • electron
     • proton -1
       • neutron 1
   • structure
     • protons and neutrons in the tiny nucleus at the centre
     • electrons and neutrons in the tiny nucleus at the centre
   • isotopes

3. the periodic table

   • mendeleev
     • arranged the elements in order of mass
     • realised that some elements did not fit the pattern of reactivity
       • he left gaps for some elements that had not yet been discoverd
   • newlands
