History of JEE (Main+Advance) Intermediate Course d-Block Elements
The study of d-block elements, also known as transition elements, has been an important part of chemistry for many years. The discovery of these elements and their properties has been a significant milestone in the development of chemistry.
The d-block elements were first discovered by Swedish chemist Axel Fredrik Cronstedt in 1751. Cronstedt was studying a mineral called niccolite when he discovered a new metal that he named nickel. This discovery led to the identification of other transition elements such as copper, zinc, and iron.
In the early 19th century, chemists began to recognize the unique properties of transition elements. In 1825, Swedish chemist Jöns Jakob Berzelius proposed the term “transition metal” to describe these elements, noting their partially filled d-orbitals.
The study of transition elements continued throughout the 19th and 20th centuries, with many important discoveries being made. In 1869, Russian chemist Dmitry Mendeleev published his periodic table, which organized the elements according to their properties. Mendeleev’s table helped to identify the patterns and trends in the properties of the transition elements.
