Valence Electrons and Oxygen Properties

This video tutorial explains how to determine the number of valence electrons for an oxygen atom. It presents two methods: using the periodic table and writing the electron configuration. Oxygen, found in group 16 of the periodic table, has six valence electrons. The electron configuration method confirms this by focusing on the highest energy level, which also results in six valence electrons. The video concludes by summarizing these methods.
