BC High Chemistry #____ Name:_________________________ Quantum Numbers, Electron Configuration & Periodic Table Review Key Topics □ Electromagnetic Radiation o Ground vs. excited state o Electromagnetic spectrum o Line-emission spectrum o Wavelength (___) □ Quantum Model of Atom o Frequency (____) o Heisenberg uncertainty principle o Speed of light (__) = ______m/s2 o Orbital o Photon o Quantum number Things that will be given on the test: Periodic Table C=ln E = hn Speed of Light Plank’s constant C = 3.0 x 108 m/s h = 6.626 x 10-34 JS 1. What is meant by the dual wave particle nature of light? 2. Put all the major categories we learned of the electromagnetic spectrum in order from greatest to smallest wavelength. 3. What happens to the frequency & energy of a wave as the wavelength gets shorter? 4. Using the two Bohr model of an atom templates drawn, draw a model showing how atoms release DIFFERENT wavelengths. Be sure to show the direction of an electron. 5. How do astronomers use spectroscopy to figure out what gases are present on distant planets and stars? 6. A wavelength of a beam of light is 24.0µm. a. Convert the wavelength to m. (1µm = 1 x 10-6 m) b. What is the frequency of this beam of light in s-1 ? c. What is the ENERGY of this beam of light in J? 7. A beam of light has the energy of 3.93 x 10-19 J. (see the equations at the beginning of the review guide for help). a. Calculate the frequency of this beam of light in s-1 ? b. Calculate the wavelength of this beam of light in m. c. Convert the wavelength from meters to nm. d. What color is this light? (google it) 8. Quantum Numbers Quantum # Principle Angular momentum Magnetic Spin Letter representing n (1st number) l (2nd number) m (3rd number) th S (4 number) What it tells you 9. Sublevels Sub-level “Code” number Orbitals (draw & label them) s p d f 10. Using orbital notation draw the sublevel that would represent each quantum number: a. [2, 1, -1, - ½] b. [3, 2, 1, ½ ] c. [4, 3, 0, ½ ] 11. For the following orbital diagrams write the (4 digit) quantum number. a. 4s ___ b. 5d ____ ___ ____ ____ ____ c. 7p ____ ____ ___ □ Electron Configurations: define the following o Aufbau principle o Pauli exclusion principle o Hund’s Rule o Noble gas 12.
