These is the table of Elements which tells about the periodicity of inanimate particles. Let us look back to have rememberance of our chemistry walls.
These was written by Dimitrive Mendeleev on 17th Feb 1869. United Nations General Assembly and UNESCO have decided to inaugurate 2019 as "The international year of periodic table of chemical elements ". There were many attempts by Mendeleev's fellowmates but his work was unique. He arranged the elements according to increasing atomic weights and stated the law that "The properties of all elements is the periodic properties of atomic masses ".He also left the gap in between by which the later discovered elements are placed. Later it undergone several modification and Henry Moseley in 1913 stated that the new law "The properties of all elements is the periodic functions of their atomic number ". It was not considered as a flaw by Mendeleev because the nucleus and its content proton itself was discovered in 1911 and 1917 respectively. It was said that the first version of the table appeared in Mendeleev's dream which mysteries ,but I know the reason which I will convey in my next blog post. His works would indeed be one of the most fundamental insight into the puzzles of nature for which Mendeleev would be known for eternity. Element 101 is aptly named as Mendelevium. Intense passion of the man to study science would motivate anyone. All the best for upcoming zeals of any field.
