Dmitri Mendeleev

Anyone who has ever taken Chemistry has studied the periodic table. Most people who have memorized the elements on the Periodic Table have probably not given any thought to who might have created it. In 1869, Dmitri Mendeleev published the very first periodic table. Although there were a few people who attempted to create a periodic table, none of these tables were as effective as Mendeleev’s version. Of course there was a rough period table proposed by Lothar Meyer in 1864. This periodic table was created in 1868 and was published in 1870. Mendeleev’s table was the most accurate and complete of all of them. He included elements and weights such as barium, bromide, calcium, chlorine potassium, and strontium. Since its creation, the table has been been expanded and revised over the years. He later claimed he had envisioned it in a dream. He not only created the Periodic Table, Mendeleev also created the Russian Chemical Society. Dmitri Mendeleev was born on February 8, 1834 in Tobolsk G

Dmitri Mendeleev Biography

Born on February 8 , 1834, to Ivan Pavlovich and Maria Dmitrievna Mendeleev, in Tobolsk in Serbia, Dmitri Mendeleev was one of fourteen children in the family. His father was not only extremely poor but also blind which forced his mother to take on the entire burden of the family on her rather frail shoulders. To make ends meet, she began a glass factory which unfortunately was razed to the ground. The same year Dmitri Mendeleev’s father too passed away. Mendeleev was a mere boy in high school when this catastrophe struck. Not to give up on her children’s education , his mother took the young boy and walked all the way , to Moscow for his admission at the university. Denied a place in Moscow , they next went to St. Petersburg where Mendeleev joined the Pedagogy course. Within a year his mother passed away. Left an orphan, Dmitri Mendeleev went on to complete his graduation in Math and Science and left for the Crimean Peninsula to teach. A couple of years later he returned once again to

Dmitri Mendeleev Quotes

I have no need of proof. The laws of nature, unlike the laws of grammar, admit of no exception. I suppose when my unknown elements are found, more people will pay us attention. I wish to establish some sort of system not guided by chance but by some sort of definite and exact principle. If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. This is expressed by the law of periodicity. In science we must all submit not to what seems to us attractive from one point of view or another, but to what represents an agreement between theory and experiment. The edifice of science not only requires material, but also a plan. Without the material, the plan alone is but a castle in the air—a mere possibility; whilst the material without a plan is but useless matter. We should still expect to discover many unknown simple bodies; for example, those similar to aluminum and silicon, elements with atomic weights of 65 to 75. When the elem
