Study Guide for Chapter 7 and Chapter 8 Chapter 7 1.Electromagnetic Radiation: • Know the relationship between the wavelength and the frequency. • Know the relationship between the wavelength, the frequency, and the photon energy. 2. Understand what the discrete lines in the atomic spectra mean. 3. Understand the Bohr’s model of the hydrogen atom. 4. Understand the modern model of the atom (meaning of principal energy number, types of sublevels/orbitals, sublevels possible for each principal number, number of orbitals in each sub level, maximum number of electrons in each orbital/sublevel. 5. Know how to draw orbital diagrams and write electronic configurations. • Memorize the energy order of orbitals (1s<2s<2p<3s<3p<4s<3d<4p) • Can you count the number of unpaired electrons and valence electrons in orbital diagrams or electronic configurations? • Know how to use abbreviated electronic configurations 6. Know the tendency of the ionization energy in the periodic table.
