G11 atomicstructures

  1. 1. http://www.youtube.com/watch?v=DmTeKpOrVNw<br />How Much Do We Know ?<br />
  2. 2. Syllabus<br />Atomic Structure – 4 hours SL<br />Atomic Structure – 3 hours SL<br />
  3. 3. Definitions<br />A – Atomic number: Number of protons in the nucleus.<br />Z - Mass number: Number of nucleons (protons and neutrons) in the nucleus<br />Isotopes of an element have same number of protons but different numbers of NEUTRONS.<br />
  4. 4. Isotopic Properties<br />
  5. 5. Radioisotopes<br />Dangers<br />14C<br />60Co<br />125I & 131I<br />
  6. 6.
  7. 7. Mass Spectrometer<br />Using<br />http://www.colby.edu/chemistry/OChem/DEMOS/MassSpec.html<br />And …… chemguide : )<br />Create a schematic of the mass spectrometer highlighting the function of each stage in the machine.<br />
  8. 8. Mass Spec Calculations<br />Calculate non-integer relative atomic masses and abundance of isotopes from given data.<br />
  9. 9. Electromagnetic Spectrum<br />Students should be able to identify the ultraviolet,visibleand infrared regions, and to describe the variation in wavelength, frequency and energyacross the spectrum.<br />
  10. 10. EMS<br />Using http://hyperphysics.phy-astr.gsu.edu/hbase/ems1.html<br />Comment on <br />Frequency<br />Wavelength<br />Energy<br />Something that interests you about this part of the spectrum.<br />Relative to the rest of the EMS<br />
  11. 11. Continuous and Line Spectra<br />http://library.thinkquest.org/28383/nowe_teksty/htmla/1_12a.html<br />http://www.chemguide.co.uk/atoms/properties/hspectrum.html<br />
  12. 12. What YOU MUST Know<br />Students should be able to draw an energy level diagram, show transitions between different energy levels and recognize that the lines in a line spectrum are directly related to these differences.<br />An understanding of convergence is expected.<br />Series should be considered in the ultraviolet, visible and infrared regions of the spectrum<br />
