Chemistry Jan 8, 2020 P3 Challenge- Consider a Calcium atom with 22 neutrons. Determine A) Draw the symbol complete with atomic number, mass number, and charge (if there is one.) B) Draw a Bohr model for the atom C) State the highest energy level and the number of valence elcetrons. Objective Atomic Structure/Quantum Mechanics Get out Bohr Model WS for HMK Check
Chemistry Jan 8, 2020 Objective Atomic Structure / Quantum Mechanics Agenda HMK review QM overview and video Organization of orbitals via Activity Assignment: Atomic Structure Exploration Activity
Quantum Mechanics Same as Bohr model except for how the energy levels are described. Electrons located in orbitals. Mathematical description is a wave function Schr dinger Explains the wave property of matter. Strategy to understand QM: Learn what the orbitals look like and how they re organized on H atom with activity (today) Populate the orbitals with electrons to describe other atoms using the periodic table (next time)
Shapes of Orbitals Using different shapes is one way QM creates its quantized energy levels. The more complicated the shape, the higher the energy level. Four different basic orbital shapes: s p d f Basic shapes double the number of lobes for each level: s, sphere p, dumbbell d, puffy 4 leaf clover f, complex
S, P, D, and F Orbitals Image result for d orbitals
Overview Video Orbitals, the Basics: Atomic Orbital Tutorial probability, shapes, energy; Crash Chemistry Academy https://www.youtube.com/watch?v=Ewf7RlVNBSA
Atomic Structure Exploration Activity Obtain a copy of the subshell sheets and an envelope, one set per lab table, a box of colored pencils and a pair of scissors. Complete an activity sheet for each team member. Due by end of period Submit an envelop of your atomic structure pieces labeled with all team member names Work in groups of 3-4 on the Atomic Structure Exploration Activity.
