UCR L8 Video Clip 1: Group discusses dot diagram for Ca (2+)—Part 1
Group discusses the next to last making sense question on CR-77: What do you think the dot diagram for Calcium 2+ is? Danielle suggests the diagram would have all eight dots around it—just like the dot diagram for Argon but using the symbol for Calcium. The instructor asks for some clarification and the group has a long conversation to clarify some issues. They think that when the two electrons are removed it goes back to the previous noble gas. This is Part 1 of the discussion. The next video clip continues the discussion.
UCR L8 Video Clip 4: Group discusses F(1-)
The group discusses the second making sense question on CR-79: The Fluoride 1− ion has the same number of valence electrons as what noble gas? There is some confusion about what 'valence electrons' mean in this case.
