iBDP SL Atomic Structure

1. http://www.youtube.com/watch?v=DmTeKpOrVNw How Much Do We Know ?

2. Syllabus Atomic Structure – 4 hours SL Atomic Structure – 3 hours SL

3. Definitions A – Atomic number: Number of protons in the nucleus. Z - Mass number: Number of nucleons (protons and neutrons) in the nucleus Isotopes of an element have same number of protons but different numbers of NEUTRONS.

4. Isotopic Properties

5. Radioisotopes Dangers 14C 60Co 125I & 131I

7. Mass Spectrometer Using http://www.colby.edu/chemistry/OChem/DEMOS/MassSpec.html And …… chemguide : ) Create a schematic of the mass spectrometer highlighting the function of each stage in the machine.

8. Mass Spec Calculations Calculate non-integer relative atomic masses and abundance of isotopes from given data.

9. Electromagnetic Spectrum Students should be able to identify the ultraviolet,visibleand infrared regions, and to describe the variation in wavelength, frequency and energyacross the spectrum.

10. EMS Using http://hyperphysics.phy-astr.gsu.edu/hbase/ems1.html Comment on Frequency Wavelength Energy Something that interests you about this part of the spectrum. Relative to the rest of the EMS

11. Continuous and Line Spectra http://library.thinkquest.org/28383/nowe_teksty/htmla/1_12a.html http://www.chemguide.co.uk/atoms/properties/hspectrum.html

12. What YOU MUST Know 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. An understanding of convergence is expected. Series should be considered in the ultraviolet, visible and infrared regions of the spectrum
