Aufbau Principle, Electron Configurations, and Ionization Energy
Lesson Outline
We reviewed the concept of ionization energy and learned about the associated periodic table trend and how to account for the out of trend EI values for boron and oxygen. We also clarified terminology such as inner core and valence electrons, and reviewed the relative energy levels of electron shells and subshells.
This session was focused on the relationship between quantum numbers and electron configurations of atoms in their neutral, ground state. Netra practiced writing quantum numbers given electron configurations and correlated given quantum numbers with the type and orientation of the occupied electron orbital.
Reviewed and practiced writing electron configurations for representative elements, transition metals, and exceptions to the Aufbau principle. Also, reviewed the relationship of quantum numbers to electron configurations and went over practice exercises to reinforce these concepts.
Netra has a good grasp of electron configurations utilizing the Periodic Table.
This lesson went over electron configurations of the elements, quantum numbers, shapes and energies of electron orbitals, and correlation to the periodic table.
Topics reviewed included the structure of the atom; the mass and charge of protons, neutrons, and electrons; the meaning of atomic number, mass number, and isotope and calculations to determine atomic weights of elements.
We went through multiple concepts that will be on her exam. She waited long to start studying for these exams, and there were too many topics to complete everything in one day, but, we worked through differentiation (basic, natural log, exponential of base e, chain rule, product rule, and quotient rule), binomial probabilities (pdf, cdf), calculator tricks (graphing equations, finding max's and min's, finding intersections, finding zeros), etc.
