Valence Electrons and the Periodic Table

This chemistry video tutorial provides a basic introduction into valence electrons and the periodic table. It explains how to determine the number of valence electrons and core electrons in an element by drawing the Bohr model of an atom, by writing the electron configuration of the element and by using the periodic table.
