Dmitri Mendeleev's Life And Accomplishments

475 Words2 Pages

Dmitri Mendeleev was born in Tobolsk Siberia in 1834. Dmitri died in 1907. One morning he was eating porridge in his kitchen and he spilled it on his fresh new shoes. Not wanting to swear he yelled out a science word and thought it sounded cool. Thought he was super mad about his fresh new shoes getting dirty he decided to look into the word. He became very interested and studied it. Dmitri Mendeleev studied the word at St. Pittsburg and graduated in 1856. Dmitri found the rest of the periodic table. There were only 60 elements on the periodic table when Mendeleev started his work. When Dmitri Mendeleev started there were a lot of mistakes so he had a lot of work to do before he was done. Dmitri did an equation to find where the individual elements were placed on the periodic table. Mendeleev said that the atomic weight is the equivalent weight times the valency. Dmitri had used his now calculated atomic weight which is now called the atomic mass to place each element. Dmitri Mendeleev was never awarded a nobel prize for his accomplishments but the one hundred and first element was named after him. Mendelevium was the one hundred and first element and was named after Dmitri Mendeleev for his accomplishments. …show more content…

Mendelevium has and atomic number of 101. Mendelevium has a melting point of 1521of or 827oc. Mendelevium is a radioactive metal which only a few atoms have been created. Mendelevium is only being used for research. Mendelevium is not a naturally occurring element which means it is made in a lab. Mendelevium is made by bombarding einsteinium with alpha particles which are identical to a helium ion. In 1955 Albert Ghiorso, Bernard Harvey, Gregory Choplin, Stanley Thompson, and Glenn Seaborg made seventeen atoms of Mendelevium. Today it is possible to produce millions of Mendelevium atoms. The longest living isotope is Mendelevium-260 which has a half life of 28

While others thought it was a waste of time he found “As we know today, when a beam of electrons strike an atom, the beam punches out the atom’s own electrons, leaving a hole, Electrons are attached to an atom’s nucleus because electrons and protons have opposite charges, and tearing electrons away from the nucleus is a violent deed” (Kean123). Mosely began to fine tune and hunt for the missing elements, creating the atomic number, determining

Ancient scientist like Democritus and Leucippus proposed the idea of the atom(Doc.1). They were the first to start the long train of ideas and knowledge that brought us to the view of the modern atom(O.I). Since then, scientist such as John Dalton and Dmitri Mendeleyev have made huge leaps in the field of atomic science. John Dalton published the atomic theory of matter(Doc.1). Dmitri Mendeleev created the periodic table that modern scientist use daily(Doc.1).

On August 26, 1743 Antoine Laurent Lavoisier was born. Lavoisier is considered to be one of the major fathers of chemistry because of his multiple advancements in chemistry during his life. There were many different instances where Lavoisier furthered the understanding of the scientific community. Throughout his life Lavoisier has helped with establishing a naming system for chemical substances, introduced the Law of Conservation of Mass, concluded that sulfur was an element, discovered that there was “oxygène” in the air that helped with combustion, and many other discoveries. During his lifetime, the French Revolution was taking place.

Before he resigned, though, Dmitri wrote his own textbook because he did not find one suitable for his students’ needs (Principles of Chemistry). Having an extensive amount of free time after quitting his job, Mendeleev accomplished many things. His biggest achievement is developing the order of periodic table of elements. Virtually all previous attempts failed as they were either too simplistic or they were too inconsistent. He organized the sixty-three known elements at the time by atomic mass.

Essay On Vanadium

The Element Vanadium and its Uses Vanadium was discovered by Andrés Manuel del Rio, a Mexican chemist, in 1801. Rio sent samples of vanadium ore and a letter describing his methods to the Institute de France in Paris, France, for analysis and confirmation. Unfortunately for Rio, his letter was lost in a shipwreck and the Institute only received his samples, which contained a brief note describing how much this new element, which Rio had named erythronium, resembled chromium. Rio withdrew his claim when he received a letter from Paris disputing his discovery. Vanadium was rediscovered by Nils Gabriel Sefstrôm, a Swedish chemist, in 1830 while analyzing samples of iron from a mine in Sweden.

John Rutherford's Contribution To The Atomic Theory

The discovery of the nucleus helped him find that atoms are mostly a bunch of empty space. He measured the nucleus by measuring the angles of scattering and using mathematical modelling found that the nucleus is less than 10-14m in diameter. Most important, he discovered the proton because of that. He came to the conclusion that, “The alpha particles were being scattered by a large amount of positive charge concentrated in a very small space at the center of the gold atom” (Tretkoff, Ernie). This discovery is so important because protons are what define what element an atom is.
