Practice Problems – Test 2 Chem 1A Fall 2010 1. Write the electron configuration of P, and construct and fill an energy level diagram for the orbitals in the atom. Make sure to label the energy axis. 2. In an alternate universe, the magnetic quantum number does not take on negative values such that m l = 0, 1, … , l . The rules for all the other quantum numbers are the same as our universe. a. Sketch the shape of the alternate universe periodic table for the first 26 elements. Number the elements rather than giving them symbols. b. Give the atomic number and complete electron configurations for the second and third noble gases in this table. Atomic # _____ Electron configuration: __________________________________________ Atomic # _____ Electron configuration: __________________________________________
