Periodic Trends in Chemical Properties

The video explores the chemical properties of elements, focusing on valence and oxidation states. It explains how electron configuration affects reactivity and provides examples of calculating oxidation states. The video also discusses the unique properties of second period elements and their diagonal relationships. Finally, it examines periodic trends in chemical reactivity, highlighting the differences in metallic and non-metallic character across periods.
