This video from MooMooMath and Science discusses transition elements, which are found in groups 3 through 12 of the periodic table. These elements have an incomplete d subshell and serve as a bridge between the two sides of the table. The video explains the properties of transition metals, including their hardness, metallic appearance, and high melting and boiling points. It also covers the inner transition metals, lanthanides, and actinides. The video concludes with a note on the reactivity and electron configuration of transition metals, highlighting their unique characteristics compared to other elements.
