General Chemistry - Ionization Energy | Periodic Trends & Exceptions | 7.2 General Chemistry

Ionization Energy Chad provides a comprehensive lesson on Ionization Energy. The lesson begins with the technical definition of Ionization Energy as well as the general periodic trend for the 1st Ionization Energy which increases up a group and from left to right across the periodic table. Notable exceptions to the general trend that students are usually responsible for knowing are then covered and explained. The lesson is concluded with a discussion of successive Ionization Energies (2nd, 3rd, 4th, etc.) when multiple electrons are removed from an atom. The large difference in the ionization energy of a valence electron and a core electron is pointed out and explained, and Chad shows how to identify which element might have the highest 2nd Ionization Energy, a common test question. I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page.
