Title: Electron Configuration
Description: Honors Chemistry
October 19, 2020

Introduce Electron Configuration

Developed electron configuration pattern.

Draw out Bohr-Rutherford models of the atom

Compare Bohr model (orbits) and quantum mechanical model (orbitals) of atom
        (look at filling order PowerPoint)
     terms:  orbital vs. orbit;  (orbitals:  s, p, d, f-orbitals)
                 Pauli exclusion principle (spin-up / spin-down);
                Aufbau principle (filling order from bottom of atom --> out);
                Hund's rule (maximum number of occupied orbitals);


Demonstration:  spring to show wave nature of light

Introduce quantum mechanical model of atom
     orbit vs. orbitals  
            an orbit is a fixed path an electron rotates in; an orbital is a probable region in space the electron may be found in (e.g. s- p-, d-, f-orbitals)
     write out electron configuration of first 20 elements.
     Show 'crutch" for filling order


                    ENERGY LEVELS AND SUBLEVELS
                                   
Objective:  To state the energy sublevels within a given energy level.
                                    Objective:  To state the maximum number of electrons that can occupy a given energy level and sublevel.
                   
QUANTUM MECHANICAL MODEL OF THE ATOM
                                   
Objective:  To list the order of sublevels according to increasing energy.
                                    Objective:  To write the predicted electron configurations for selected elements.
