Check out the full Atomic models and periodicity playlist here: https://youtube.com/playlist?list=PLSQl0a2vh4HAYCvTHhMGsNvLS-btVPXRw&si=ewZ4I_TtM8MDBokW The cations and anions in an ionic solid are arranged in a lattice structure that maximizes the attractive forces between opposite charges and minimizes the repulsive forces between like charges. In this video, we'll learn how to represent the structure of an ionic solid using a particulate model. Sections: 00:00 - How ions form crystals 00:30 - Visualizing ionic arrangements 01:27 - Forces driving ion arrangement 02:07 - Checkerboard lattice structure 02:54 - Introducing rubidium bromide 03:32 - Electron configuration of ions 04:20 - Comparing ion sizes 05:02 - Drawing a particulate model ------------------ Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!
