Learn the fundamentals of the modern periodic table, including organization by increasing atomic mass and atomic number, columns (groups) and rows (periods), main group and transition elements, regions of metals, nonmetals, and metalloids. Explore the named families, including alkali metals, alkaline earth metals, chalcogens, halogens, and noble gases, as well as the blocks of elements and sub-periods like lanthanides and actinides. This guide provides essential insights into the structure and classification of elements within the periodic table for better understanding.
