        Metals
        
        Ductile (wires)
        
        Gold,Silver,Copper, Iron, Potassium,Sodium , Mercury(Liquid at Room Temperature)
        
        Good Conductors-heat,electricity
        
        Malleable(thin Sheets) + Sonorous (Ringing sound)
        
        Lustre (shine)-- Silver, grey or Golden Yellow
        
        Non Metals
        
        Poor Conductors-heat,electricity
        
        Non lustrous,Sonorous,Malleable
        
        Variety of colours
        
        Hydrogen,Oxygen,Carbon(Coal,Coke),Bromine,Iodine,Chlorine
        
        Metalloid
        
        Intermediate properties Metals and Non Metals
        
        Ex: Boron, Silicon,Germenium
      - Antoine Lavoisier-defined experimentally
      - Robert Boyle (1661)-first coin term
      - Cannot be broken into simpler sbstances
    - - Fixed Proportion, Properties differ from constituents
      - Two or more elements chemically combined
      - composite same throughout, separated only by chemical
        or electrochemical reaction
      - Ex-Iron+Sulphur(heated)= Iron Sulphide(Compound)
- - - - Uniform composition throughout
      - Homogeneity at particle level
      - Ex: Salt in water,sugar in water, Lemonade,soda water
      - components
        
        Solvent: Dissolves other components(larger amount)
        
        solute: Dissolved in solvent (lesser quantity)
      - Examples of solution
        
        Sugar in water(solid in liquid)
        
        Aerated drinks(Co2 in water),(gas in liquid)
        
        Air(gas in gas, oxygen 28%, Nitrogen 78%)
        
        Alloys: solid solutions (Brass=Zinc 30%, Copper 70%)
