Bozeman Science: Ap Chemistry: Periodicity

9th - 10th
In this video, Paul Andersen explains why atoms in the periodic table show trends in ionization energy, atomic radii, electronegativity and charge. All of these trends are explained through Coulomb's Law. A brief description of Dmitri...

Bozeman Science: Ap Chemistry: Atomic Models

9th - 10th
Paul Andersen explains how the atomic model has changed over time. A model is simply a theoretical construct of phenomenon and so when we receive new data we may have to refine our model. Ionization energy data resulted in the formation...
