Valence Electrons and Hydrogen Properties

This video tutorial explains how to determine the number of valence electrons for hydrogen. It covers two methods: using the periodic table and writing the electron configuration. The periodic table method involves looking at the group number, while the electron configuration method involves understanding the atomic number and energy levels. Both methods conclude that hydrogen has one valence electron.
