  3. 3. In Charge of Leading Discussion 1. Log into Learning Point 2. Daily Assignments 3. This Week 4. Open “Elements, Compounds and Mixtures” slide share 5. Use your abbreviation skills 6. R & R – Pgs 1 & 2
  4. 4. Elements are pure substances made of only one kind of atom. 1. As we have learned, atoms are tiny structures found in all matter. 2. Most substances contain many different atoms. 3. It is how those atoms are arranged that determine whether you have an element, compound or mixture.
  5. 5. 1. One kind of atom 2. Pure (because all particles are the same) 3. Smallest particle to retain identity of the element 4. Separated only in nuclear reactions
  6. 6. Particles look like: Every atom looks exactly the same w/ the same number of protons Oxygen Hydrogen 1 1 1 8 8 8
  7. 7. Example: Your Example? Aluminum: Every atom of aluminum in this can is exactly the same
  8. 8. 1. Two or more kinds of atoms chemically bonded 2. Pure (because all particles are the same) 3. Smallest particle to retain the identity of the compound (SET RATIO of particles) 4. Separated or rearranged in chemical reactions
  9. 9. Particles look like: Every compound looks exactly the same w/ the same set ratio Carbon Dioxide – CO2 Sodium Chloride - NaCl
  10. 10. Example: Your Example? Salt: Every molecule of the compound NaCl is exactly the same
  11. 11. 1. Two or more elements and/or compounds blended together physically 2. Not pure (because all the particles are not the same) 3. Separation through distillation, magnetic, evaporation, density, or particle size 4. No set ratio
  12. 12. Particles look like: Each particle keeps its own identity….they are just “blended” together Mixture #1 Mixture #2
  13. 13. Examples: Your Examples? Heterogeneous: Different components are easy to see in this type of blending Homogeneous: Different components are difficult to see because they are evenly distributed
  14. 14. Compound
  15. 15. Mixture
  16. 16. 1. A solution is a mixture where all the components blend together to look like one substance. 2. A solution is a homogeneous mixture that appears to be a single substance. 3. The solution is composed of particles of two or more substances that are distributed evenly among each other and have the same appearance and properties throughout.
  17. 17. 1. In solutions, the SOLUTE is the substance that is being dissolved and usually is the smaller quantity in the mixture. 2. The SOLVENT is the substance in which the solute is dissolved and usually is the larger quantity in the mixture. 3. It is the SOLVENT that is doing the dissolving. 4. Go to page 144-145 in your textbook: Give examples of solutions in various states.
  18. 18. • Homogeneous: 2 or more things evenly blended and disappear into each other. • Solute – Smaller quantity by % • Solvent – Larger quantity by % • Solution – a homogeneous mixture
  19. 19. • Heterogeneous: 2 or more things put together and still can be seen. • No set RATIO.
  20. 20. Have you ever put sugar into lemonade and seen the grains of sugar sink to the bottom and not dissolve? This is because the lemonade (solution) is supersaturated. In other words, there is not enough water (solvent) to completely dissolve the sugar (solute). Temperature and Pressure can affect saturation levels.
  21. 21. Saturation Level What does this mean? What does this look like? (color) Unsaturated Saturated Supersaturated •Mixture contains more solvent than solute •Able to dissolve more solute •Mixture contains the % of solute completely dissolved by solvent •No able to dissolve more solute •Mixture contains the % of solute unable to be dissolved by the % of solvent at the given temp. High temp usually = higher solubility
  22. 22. 1. We now know the definition of Element, Compounds & Mixtures 2. What do their particles look like?
  23. 23. 1. You should have completed pgs. 1-3, at minimum, of Elements, Compounds and Mixtures – Thursday Due Date 2. Bohr Model and Lewis Dot Diagrams + Density Review – Was Due on Friday – 1st grade of 4th quarter
