Answer 1

Electron Configurations Section 5.3  

2  Objectives Apply the Pauli Exclusion Principle, the Aufbau Principle, and Hund’s Rule to write electron configurations using orbital diagrams and electron configuration notation. Apply the Pauli Exclusion Principle, the Aufbau Principle, and Hund’s Rule to write electron configurations using orbital diagrams and electron configuration notation. Define valence electrons and draw electron-dot structures representing an atom’s valence electrons. Define valence electrons and draw electron-dot structures representing an atom’s valence electrons.  

3  Electron configuration: the arrangement of electrons in an atom Electrons tend to assume an arrangement that gives the atom the lowest possible energy. Why? Electrons tend to assume an arrangement that gives the atom the lowest possible energy. Why? This arrangement is the ground-state electron configuration. This arrangement is the ground-state electron configuration. Three (3) rules define how electrons can be arranged in an atom’s orbitals. Three (3) rules define how electrons can be arranged in an atom’s orbitals.  

4  Rule #1 The Aufbau Principle states that each electron occupies the lowest energy orbital available. The Aufbau Principle states that each electron occupies the lowest energy orbital available. An aufbau diagram show the sequence of orbitals from lowest to highest energy. An aufbau diagram show the sequence of orbitals from lowest to highest energy.
