Mission MAM7 Core and Valence Shell Electrons

Mission MAM7 pertains to core and valence shell electrons. Students must determine the number of core and valence shell electrons for main group elements if given the element name, an electron configuration, the group the element is in, or an electron shell diagram.

• The student should be able to explain the distinction between a core and a valence shell electron.
• The student should be able to identify the number of core and valence shell electrons in an atom of an element.
