Download or read book At Astatine written by Hans K. Kugler and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astatine is - besides radon and francium - the only natural radioelement which only has short-Lived isotopes, thereby excluding experiments with . . weighable" amounts of the element. This implies that all available data on physics and chemistry of this element are 12 16 based on experiments on the tracer scale with 10- to 10- g - and this will also not change in future because no longer-Lived isotopes as yet known are to be expected. Due to the fact that the only isotope of At occurring in the natural decay series, 219At, results from the 0. 005% a-branching of 223Fr which itself is produced by the only 1. 38% a-branching of 227 Ac - a member of the 235U series - there is no chance to recover substantial amounts of 219At from natural sources for sCientific research of At. All studies, therefore, are being done with the isotopes 209At to 211At having half-lives in the few hours region and being obtained by irradiation of bismuth with a-particles via (a,xn) reactions or by proton irradiation of heavy elements via spallation reactions. The mostly used isotope is 7. 22 h 211At. The fast separation of the obtained At isotopes is no very difficult procedure and is either being done by wet adsorption-precipitation techniques or making use of its high volatility by destilling in air.

Available in PDF, EPUB and Kindle. Book excerpt: A readable, informative, fascinating entry on each one of the 100-odd chemical elements, arranged alphabetically from actinium to zirconium. Each entry comprises an explanation of where the element's name comes from, followed by Body element (the role it plays in living things), Element ofhistory (how and when it was discovered), Economic element (what it is used for), Environmental element (where it occurs, how much), Chemical element (facts, figures and narrative), and Element of surprise (an amazing, little-known fact about it). A wonderful 'dipping into' source for the familyreference shelf and for students.

Download or read book Women In Their Element Selected Women s Contributions To The Periodic System written by Lykknes Annette and published by World Scientific. This book was released on 2019-08-05 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: This year we celebrate the 150th anniversary of Mendeleev's first publication of the Periodic Table of Elements. This book offers an original viewpoint on the history of the Periodic Table: a collective volume with short illustrated papers on women and their contribution to the building and the understanding of the Periodic Table and of the elements themselves.Few existing texts deal with women's contributions to the Periodic Table. A book on women's work will help make historical women chemists more visible, as well as shed light on the multifaceted character of the work on the chemical elements and their periodic relationships. Stories of female input, the editors believe, will contribute to the understanding of the nature of science, of collaboration as opposed to the traditional depiction of the lone genius.While the discovery of elements will be a natural part of this collective work, the editors aim to go beyond discovery histories. Stories of women contributors to the chemistry of the elements will also include understanding the concept of element, identifying properties, developing analytical methods, mapping the radioactive series, finding applications of elements, and the participation of women as audiences when new elements were presented at lectures.As for the selection of women, the chapters include pre-periodic table contributions as well as recent discoveries, unknown stories as well as more famous ones. The main emphasis will be on work conducted in the late 19th century and early 20th century. Furthermore, the book includes elements from different groups in the periodic table, so as to represent a variety of chemical contexts.'As with the discoveries themselves, bringing these tales of female scientists to light has taken much teamwork, including by contributors Gisela Boeck, John Hudson, Claire Murray, Jessica Wade, Mary Mark Ockerbloom, Marelene Rayner-Canham, Geoffrey Rayner-Canham, Xavier Roqué, Matt Shindell and Ignacio Suay-Matallana.Tracing women in the history of chemistry unveils a fuller picture of all the people working on scientific discoveries, from unpaid assistants and technicians to leaders of great labs. In this celebratory year of the periodic table, it is crucial to recognize how it has been built — and continues to be shaped — by these individual efforts and broad collaborations.'Nature 565, 559-561 (2019)
