Mendeleevs Periodic Table

The video tutorial introduces the concept of chemical elements as the building blocks of matter, comparing them to an alphabet. It highlights the arbitrary nature of the traditional alphabet and contrasts it with the logical arrangement of elements in the periodic table, which is based on universal laws. The video focuses on Dmitri Mendeleev's significant contribution to chemistry by organizing the periodic table, explaining how he arranged elements by atomic weight and predicted the properties of undiscovered elements. Mendeleev's predictions were remarkably accurate, as demonstrated by the later discovery of elements like germanium and gallium.

How did Mendeleev's approach to organizing elements differ from the traditional alphabet?

What were some of the elements that Mendeleev predicted, and what were their original names?
