Add 4 lone pairs. Lone pairs will wobble back and forth perpetually, rather than finding a stable position. See video clip here:\r\nhttps://drive.google.com/file/d/0B4Hie_375TsjUU0za3VmT3hyTlE/view?usp=sharing\r\n\r\n(2) A molecule with 3 lone pairs and 3 bonded atoms where the lone pairs and the atom in the same plane can be set rotating perpetually. See video clip here:\r\nhttps://drive.google.com/file/d/0B4Hie_375TsjenRHMHR2TVN2VDg/view?usp=sharing\r\nI haven't been able to reproduce this one, but it cropped up while I was getting ready for a student interview, and we also saw it during the interview as well. \r\n\r\nSeverity: High - both issues lead would students to draw conclusions about stability of the molecules that aren't true.
