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.
