In this video, Mr. Krug shows students various applications of electron configurations, including the difference between ground state and excited state configurations, how to map electrons in an atom, and how to determine the number of valence electrons in an atom. He concludes the video by showing students how to use the periodic table of the elements to predict the number of valence electrons in an atom of an element.
