Modern Periodic Table

The video tutorial discusses the development of the periodic table, starting with Mendeleev's classification of elements based on atomic weight and properties. It highlights the limitations of Mendeleev's table, such as the placement of elements with higher atomic weights before those with lower weights and the lack of space for noble gases and isotopes. The modern periodic law, which arranges elements by atomic number and electronic configuration, is introduced. The video also explains the IUPAC naming system for newly discovered elements, using numerical roots to derive names based on atomic numbers.

What are lanthanides and actinides, and how were they treated in Mendeleev's table?

How did Mendeleev's periodic table differ from the modern periodic table?
