AP Chemistry Review: Unit 1 (Atomic Structure and Properties)

Fundamental Concepts and Atomic Structure00:00:23

Introduction to atomic structure, defining atoms as the smallest unit of an element, distinguishing between pure substances and mixtures, and explaining the arrangement of protons, neutrons, and electrons.

Isotopes, Ions, and Mass Spectroscopy00:06:38

Explanation of isotopes as atoms with varying neutron counts, the definition of ions based on electron gain or loss, and how mass spectroscopy is used to determine isotopic abundance and atomic mass.

The Mole, Molar Mass, and Stoichiometry00:10:46

Defining the mole and Avogadro's number for macroscopic calculations, and how to convert between mass and moles using molar mass, including empirical and molecular formula derivation.

Electron Configurations and Quantum Mechanics00:19:30

In-depth look at Coulomb's law, quantum numbers, atomic orbitals (s, p, d, f), the Aufbau principle, Hund's rule, and how to determine electron configurations for any element.

Periodic Trends00:29:47

Analysis of predictable periodic trends including atomic radius, ionic radius, ionization energy, photoelectron spectroscopy, electron affinity, and electronegativity.
