In 1869, Dmitri Mendeleev discovered the periodic law, which led to the creation of the Periodic Table of elements. He organized elements based on their Atomic Mass and chemical properties, revealing a periodic pattern that predicted the existence and properties of undiscovered elements. Mendeleev's work laid the foundation for modern chemistry and significantly advanced the understanding of elemental relationships.
Dimitri Mendeleev was born on February 8th, 1834.
Frederick Miescher discovered DNA in 1869 while studying the nucleus of white blood cells. He isolated a new chemical substance from cell nuclei that he called "nuclein," which we now know as DNA.
The periodic table was formed in the 19th century by Dmitri Mendeleev in 1869. Mendeleev organized the elements based on their properties and atomic weights, creating the foundation for the modern periodic table we use today.
