Dmitri Mendeleev's First Periodic Table Presentation
Dmitri Mendeleev introduced his periodic table to the Russian Chemical Society in St. Petersburg, showcasing the organization of chemical elements based on atomic mass and properties. His innovative table not only represented a significant advancement in chemistry but also predicted undiscovered elements. Mendeleev's framework allowed scientists to see the relationships among elements and set the cornerstone for modern chemical science.

In 1861, Sir William Crookes announced the discovery of thallium, a new chemical element. He identified it through his studies of uranium minerals, utilizing a spectroscope to analyze the emitted light and detect the unique spectral line characteristic of this element. Crookes's meticulous experimentation led him to isolate thallium, which he named after the Greek word for green, 'thallos', reflecting the bright green line in its spectrum. This discovery expanded the periodic table and contributed to the field of chemistry.
