Atomic orbital theory is a difficult subject for many high school and beginning undergraduate students, as it includes mathematical concepts not yet covered in the school curriculum. Moreover, it requires certain ability for abstraction and imagination. A new atomic orbital model "the chocolate shop" created "by" students "for" students is presented. This model, which is the result of student imagination, is more tangible, being strictly related to daily life. The model has proved useful in teaching the structure of the atom in a 5th grade class. As for any other model, the chocolate model has its advantages and limitations, which are discussed.
