This is a free response question written in format like AP does. This question revolves around atomic structure concepts and calculations students would learn in a PreAP Chemistry course. Each successive part (parts a-f here) of any FRQ potentially builds on itself and emphasizes a deeper understanding of the topic.
The first page is the question which I give to students as part of their atomic structure unit test, but this could be used as a quiz, classwork, or homework assignment. The second and third pages are scoring guidelines also written in an AP format.
