2) Performance on the in-class activity (clicker scores or hand-graded worksheet)
Students generally score on average 70% or higher on the pre-lecdure quiz, and on average 70% or more of students correctly answer the in-class clicker questions.
This is a flipped classroom module that covers the concepts of quantum numbers, and radial and angular nodes. This activity is designed to be done at the beginning of the typical first quarter/first semester general chemistry course (for an atoms first approach; if instructors use a traditional course structure this unit is likely done towards the middle/end of the first quarter/semester). Students will be expected to have learned the following concepts prior to completing this activity:
a) quantization of energy in the atom and the Bohr model of the atom;
b) how the wave/particle duality of electrons was described by de Broglie;
c) how the wave/particle duality of electrons was used by Schrodinger to develop the quantum mechanical model of the atom;
d) how radial probability distribution was used to generate the idea of atomic orbitals, and orbital probability surfaces.
a) describe the meaning of the quantum numbers n, l, and ml;
b) determine the values of the quantum numbers n, l, and ml;
c) describe the meaning of radial and angular nodes;
d) determine the number of radial and angular nodes on different types of atomic orbitals;
e) begin to understand the correlation between the quantum numbers and the total number of atomic orbitals for a given atom, and how the periodic table can be used to build up the overall orbital structure for an atom.
