					Chapter 3 – Elements, Mixtures
        & Compounds
        Chapter 3 – Section 1
• _____________= pure substance that can not
  be separated into simpler substances by
  physical or chemical means

• ______ ________________= only one type of
  particle
• Each element has unique properties that allow
  us to identify them
• Physical properties that help us identify:
  D__________, M____, B____, or H_________
  (called ______________ __________ of
  matter)
• Also chemical properties
• Elements put into groups, whether or not they
  share enough common properties.
• If you know what category something is found
  in, then you should know some properties of
  that substance.
• Metals
  - ____________
  - good conductors of e________ and
  t_________ ___________
  - __________________
  - _____________
  - many uses throughout daily life
• Nonmetals
  - ________
  - ______ conductors
  - _____________
  - ___________________
  - not very common
• Metalloids (aka Semiconductors)
  - properties of _________
  - some are shiny / some dull
  - ___________ malleable and ductile
  - Silicon, Antimony & Boron
        Section 2 - Compounds
• Compounds = _______ ______________
  composed of 2 or more elements that have
  been _______________ ______________
  (C&C)
     - they must undergo a chemical change
     - Not random; specific ratio of components
     - Unique set of properties that are
     different from the elements’ properties
• Can be broken down into simpler substances
  (elements)
• ONLY through chemical changes NOT physical
  changes
• Compounds are everywhere
• P__________ = found in many things, so vital
  to life
• _______ or _________ is a compound
• Manufactured compounds help many things
Examples of compounds?
         Section 3 - Mixtures
• Mixture = combo of two or more substances
  that are NOT __________ _______________
     - Substances retain _______________
     - Can be _________________ separated
     - Examples = distillation, magnet, or
     centrifuge
     - No ____________ _________
• Solution = a mixture that appears as one
  single substance, but is composed of two or
  more that are evenly distributed
  (homogenous)
      - __________ = substance dissolved
      - __________ = the substance in which the
      solute is dissolved
      - Soluble vs Insoluble
      - Particles are extremely small, never settle
      out nor filter out
• ____________= Amount of solute in a solvent
     - Acid example
     - Concentrated or Dilute
     - Saturated vs Unsaturated
• Solubility = Amount of _________needed to
  make a saturated solution, using a given
  amount of _____________
     - Methods to dissolve faster
           1) M_______
           2) C_________
           3) H__________
• Suspensions = mixture in which particles are
  dispersed, but DO settle out
      - Particles are_____________

• ________________= mixture in which
  particles are dispersed, but do NOT settle out
     - Well mixed and small particles
     - Examples = Milk, mayonnaise, stick
     deodorant, gelatin & whipped cream
     - Large enough to scatter light
     - No filtration
