Atomic chemistry is a core component of the MCAT, essential for understanding molecular behavior and periodic trends.

In this episode, host Sam Smith explores key concepts in atomic chemistry, including the intricacies of quantum theory, hybridization, and molecular geometry. You'll gain insights into electron configuration, periodic trends, and the role of quantum numbers in describing electrons. Sam also discusses the significance of nuclear decay, from alpha to beta and gamma decay, and how it impacts atomic structure.
