Study tips and resources for Chapter 11 – Physical Chemistry by Laidler, Meiser, Sanctuary
The foundations of quantum mechanics (Section 11.3) of the Physical Chemistry textbook, introduces the idea that electrons must be considered as both a particle and as having wave characteristics. This concept is absolutely key to understanding quantum mechanics and yet is sometimes hard to get a handle on.

The discovery of atomic structure was the key that unlocked the door to modern understanding of structure and reactivity. Let’s take a moment to review a bit of history before Bohr’s monumental discovery. Continue reading
When learning about quantum numbers for the first time, it can be overwhelming and confusing. However, in all my years of teaching, no other topic so feared at first; has been so rewarding and enjoyed after the “aha” moment passed. Continue reading
