### Wednesday Lecture

I missed the lecture for today (Wednesday). Could somebody give me a basic summary of what topics the professor went over?

### Re: Wednesday Lecture  [ENDORSED]

In class today (July 3) I covered:

• Know how to solve problems using Heisenberg’s indeterminacy equation.
• Understand the relationship between Schrodinger's equation, wave functions, and orbitals.
• Describe and identify s-, p-, and d-orbitals.
• Describe the interpretation of atomic orbitals in terms of probability.
• Name and explain the relationship of each of the four s-, p-, and d-orbitals to the properties of electrons in these states.
• List the allowed energy levels of a bound electron in terms of the quantum numbers n, l, and ml.
• State how many orbitals of each type are contained in the shell corresponding to a given principal quantum number and how many electrons can be accommodated in those orbitals.

See my class website, Outline 2: The Quantum World (https://lavelle.chem.ucla.edu/wp-conten ... _World.pdf)

On Friday, July 5, I will cover the remaining Quantum topics:

• Describe the factors affecting the energy of an electron in a many-electron atom.
• Write the ground-state electron configuration for an element or ion (Aufbau Principle).
• Use the periodic table to predict and explain trends in atomic radius, ionic radius, ionization
energy, and electron affinity.

Today, July 3, I sent detailed email to the class. Did students receive it?
