Not as many students opted to take the periodic table quiz today. Those that did all earned over a 100%, though. We continued our topic of atomic structure today by introducing ions, or charged atoms that have either gained or lost one or more electrons. We watched a third straight http://www.brainpop.com/ video today, this time on ions. We ended the period by completing worksheet 3-16, which we will check at the beginning of tomorrow's class.
No homework was assigned. Test on Thursday, December 10th.
