Mendeleev's Periodic Table

The video introduces the concept of chemical elements as the building blocks of matter, akin to an alphabet for chemists. It discusses the creation of new elements and the challenges of organizing them, leading to Dmitri Mendeleev's development of the periodic table. Mendeleev arranged elements by atomic weight and discovered patterns, predicting properties of undiscovered elements with remarkable accuracy. His work laid the foundation for the modern periodic table, highlighting its logical structure compared to the arbitrary order of the traditional alphabet.

What were the names of the elements Mendeleev predicted, and what were their corresponding known elements?

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