Transition Elements and Alkaline Metals

This video tutorial explores the properties and reactivity of transition elements compared to alkaline metals. It covers the placement of metals in the periodic table, the characteristics of alkaline metals, and the unique features of transition elements, including their high melting points, density, and ability to form ions with different charges. The video also highlights the practical uses of transition elements, such as their role as catalysts and their formation of colored compounds.
