Exploring the Periodic Table Structure

This video tutorial by Kaeleigh provides an in-depth look at the periodic table, explaining its organization into groups and periods. It covers various types of elements, including alkali metals, alkaline earth metals, transitional metals, post-transitional metals, lanthanides, actinides, metalloids, nonmetals, noble gases, and unknown elements. The tutorial also explains how to read an element box, detailing atomic numbers, symbols, and masses. The video aims to enhance understanding of the periodic table's structure and the properties of different elements.
