141. Dimitri Mendeleev Contains a biography about the man who discovered the periodic law and developed the periodic table. http://www.zephyrus.co.uk/dimitrimendeleev.html

Dimitri Ivanovitch Mendeleev So, who was Dimitri Mendeleev The youngest, of at least, fourteen children, Dimitri Ivanovitch Mendeleev was born at Tobolsk Siberia , on 7th February, 1834 . His father, Ivan, was the director of the local gymnasium, and his mother, Marya , (born Marya Korniliev ) came from a family that had introduced glass and paper making to Siberia . Ivan died when Dimitri was quite young and Marya had to return to work in order to support her family. Through family connections, she managed the Korniliev glass factory at Aremziansk Dimitri was educated at the gymnasium in Tobolsk , where he showed great interest in mathematics and physics. He also learned a lot about glass and glass blowing from the family factory. His brother-in-law, Bessargin , was also an influence in that he taught the young Mendeleev current science topics. By the age of fourteen, Dimitri showed great scientific promise and his mother was determined that he should receive a good education. Her plans were thwarted when the glass factory was destroyed by fire. Within a few months

Previous positions in US: Bradley University and Purdue University Research In recent years there has been a worldwide upsurge of interest in philosophical aspects of chemistry. In my own work I examine the extent to which chemical concepts can be explained through fundamental theories in physics, especially quantum mechanics. I also focus on the implications of this work on chemical education and the manner in which chemistry is presented in textbooks and general chemistry courses. More specifically, I am interested in issues surrounding the teaching of atomic and electronic structure. I also work on historical and philosophical aspects of the Periodic System of the Elements and several other areas in history and philosophy of chemistry.

147. C&EN: The Periodic Table--1923 & 1998 elements. Since C EN began publication in 1923, 26 elements have beenadded to the periodic table. On nature. The periodic table. With http://pubs.acs.org/hotartcl/cenear/980112/periodic.html

January 12, 1998 Rebeccca L. Rawls T The era spans a major change in the kind of elements being discovered. Hafnium (discovered in 1923) and rhenium (in 1925) were the last elements with stable nuclei to be added to the periodic table. Beginning with technetium, discovered in 1937, the new elements are radioactive in all of their isotopes. All but one of them were "discovered" shortly after they were artificially produced through nuclear transmutation reactions, although some, such as neptunium and plutonium, were later found also to occur in nature. The Periodic Table With the discovery of hafnium, element 72, the then-new field of atomic physics was becoming crucial to the discovery of new elements. Although not a rare element, hafnium was nearly impossible to distinguish chemically from the much more common element zirconium. Dutch physicist Dirk Coster and Hungarian chemist George Karl von Hevesy used Neils Bohr's theory of how electrons fill shells and subshells within atoms to predict differences in the two elements' X-ray spectra. They then demonstrated that they could detect X-rays from both elements in a sample of a zirconium-rich ore. They named the element after Bohr's hometown of Copenhagen (Hafnia in Latin). Marguerite Perey isolated francium from uranium ore.

153. Mendel Brief biography about Dimitri Mendeleev, the developer of the periodic table. http://www.pbs.org/wnet/hawking/cosmostar/html/cstars_mendel.html

DMITRI MENDELEEV B orn in Siberia, the last of at least 14 children, Dmitri Mendeleev (1834-1907) revolutionized our understanding of the properties of atoms and created a table that probably adorns every chemistry classroom in the world. After his father went blind and could no longer support the family, Mendeleevís mother started a glass factory to help make ends meet. But just as Mendeleev was finishing high school, his father died and the glass factory burned down. With most of her other children now out on their own, his mother took her son to St. Petersburg, working tirelessly and successfully to get him into college. In the late 1860s, Mendeleev began working on his great achievement: the periodic table of the elements. By arranging all of the 63 elements then known by their atomic weights, he managed to organize them into groups possessing similar properties. Where a gap existed in the table, he predicted a new element would one day be found and deduced its properties. And he was right. Three of those elements were found during his lifetimeógallium, scandium, and germanium. They provided the strongest support for his periodic table, a cornerstone both in chemistry and in our understanding of how the universe is put together.

Soon after, Charles Glover Barkla discovered that each element has its own characteristic x-ray spectrum . He was awarded a Nobel Prize in physics for this discovery in 1917 . Sir William Henry Bragg and his son, Sir William Lawrence Bragg, were then able to experimentally prove that the discrete electron energy levels of an atom, an idea proposed by Niels Bohr, actually existed . They were awarded the Nobel Prize in physics for this in 1915 . After this groundwork in x-ray spectroscopy was established, Henry Moseley showed that each element’s characteristic x-ray energy spectrum followed the predictions of the Bohr atomic model . He developed a graphical method to display this data, now known as the Moseley diagram, which is displayed in Figure 1. This diagram was the first way that scientists were able to definitively establish the atomic numbers of the elements

159. The Periodic Table Of Dessert The periodic table of Dessert. You ve seen those charts that say, like, periodictable of the Vegetables or periodic table of the Sausages ? They annoy me. http://www.eblong.com/zarf/periodic/

The Periodic Table of Dessert A Scientific and Rigorous approach to patisserie in Full Color You've seen those charts that say, like, "Periodic Table of the Vegetables" or "Periodic Table of the Sausages"? They annoy me. Because they're not periodic. They have no vertical or horizontal correspondences. The actual periodic table of chemical elements has structure that's why it's cool. Thus: my contribution to the field. This image is scaled down quite a bit. Here are some larger views Questions? Comments?
