Walker CH301 Exam02 Materials Page 1 of 1 Worksheet: Quantum Numbers and Electronic Configuration 1. The three quantum numbers for an electron in a hydrogen atom in a certain excited state are n=4, l =2, m l =-1. In what type of orbital is the electron located? 2. Write an “address” of four quantum numbers that can definitely NOT exist in any atom (according to current theory). 3. Write the electronic configuration for an iodine atom. 4. Write the “address” of four quantum numbers that identifies the highest energy electron in the iodine atom. 5. Write the electronic configuration for each of the alkali metals. Then write a generic econfig for the alkali metals. 6. If you could summarize the valence state electronic configuration for the alkali metals, what would it be? 7. What are all the possible quantum numbers for an electron located in a 2d orbital of a H atom?

Identify the element that has quantum numbers n=3, l =1 for its valence electrons and whose m l degenerate orbitals are half-filled. 10. Write the shorthand electronic configuration for each of the jewelry metals: copper, silver, gold. 11. Predict the electronic configuration for the recently discovered elements Z=116 and Z=118. (2006; http://www.aip.org/pnu/2006/split/797-1.html) 12. Given what you know about Hunds rule and noble gases, speculate which is less stable and why: Li or N 13. Based on Hunds rule, speculate which is more reactive: P or S. Explain. 14. Which has the greater Z eff (effective nuclear charge) in each pair: 1. O or F? 2. O or S? 15. Which of the following would require less energy to lose an electron: Li or F?...
