NOBELIUM Element Symbol: No Atomic Number: 102
NOBELIUM Element Symbol: No Atomic Number: 102 An initiative of IYC 2011 brought to you by the RACI KERRY LAMB www.raci.org.au NOBELIUM Element symbol: No Atomic number: 102 The credit for discovering Nobelium was disputed with 3 different research teams claiming the discovery. While the first claim dates back to 1957, it was not until 1992 that the International Union of Pure and Applied Chemistry credited the discovery to a research team from Dubna in Russia for work they did in 1966. The element was named Nobelium in 1957 by the first of its claimed discoverers (the Nobel Institute in Sweden). It was named after Alfred Nobel, a Swedish chemist who invented dynamite, held more than 350 patents and bequeathed his fortune to the establishment of the Nobel Prizes. Nobelium is a synthetic element and does not occur in nature and has no known uses other than in scientific research as only tiny amounts of the element have ever been produced. Nobelium is radioactive and most likely metallic. The appearance and properties of Nobelium are unknown as insufficient amounts of the element have been produced. Nobelium is made by the bombardment of curium (Cm) with carbon nuclei. Its most stable isotope, 259No, has a half-life of 58 minutes and decays to Fermium (255Fm) through alpha decay or to Mendelevium (259Md) through electron capture. Provided by the element sponsor Freehills Patent and Trade Mark Attorneys ARTISTS DESCRIPTION I wanted to depict Alfred Nobel, the namesake of Nobelium, as a resolute young man, wearing the Laurel wreath which is the symbol of victory.

FRANCIUM Element Symbol: Fr Atomic Number: 87
FRANCIUM Element Symbol: Fr Atomic Number: 87 An initiative of IYC 2011 brought to you by the RACI KAYE GREEN www.raci.org.au FRANCIUM Element symbol: Fr Atomic number: 87 Francium (previously known as eka-cesium and actinium K) is a radioactive metal and the second rarest naturally occurring element after Astatine. It is the least stable of the first 103 elements. Very little is known of the physical and chemical properties of Francium compared to other elements. Francium was discovered by Marguerite Perey of the Curie Institute in Paris, France in 1939. However, the existence of an element of atomic number 87 was predicted in the 1870s by Dmitri Mendeleev, creator of the first version of the periodic table, who presumed it would have chemical and physical properties similar to Cesium. Several research teams attempted to isolate this missing element, and there were at least four false claims of discovery during which it was named Russium (after the home country of soviet chemist D. K. Dobroserdov), Alkalinium (by English chemists Gerald J. K. Druce and Frederick H. Loring as the heaviest alkali metal), Virginium (after Virginia, home state of chemist Fred Allison), and Moldavium (by Horia Hulubei and Yvette Cauchois after Moldavia, the Romanian province where they conducted their work). Perey finally discovered Francium after purifying radioactive Actinium-227 from Lanthanum, and detecting particles decaying at low energy levels not previously identified. The new product exhibited chemical properties of an alkali metal (such as co-precipitating with Cesium salts), which led Perey to believe that it was element 87, caused by the alpha radioactive decay of Actinium-227.

Microdosimetry of Astatine-211 and Xa0102708 Comparison with That of Iodine-125
MICRODOSIMETRY OF ASTATINE-211 AND XA0102708 COMPARISON WITH THAT OF IODINE-125 T. UNAK Ege University, Bomova, Izmir, Turkey Abstract.' 21lAt is an alpha and Auger emitter radionuclide and has been frequently used for labeling of different kind of chemical agents. 125I is also known as an effective Auger emitter. The radionuclides which emit short range and high LET radiations such as alpha particles and Auger electrons have high radiotoxic effectiveness on the living systems. The microdosimetric data are suitable to clarify the real radiotoxic effectiveness and to get the detail of diagnostic and therapeutic application principles of these radionuclides. In this study, the energy and dose absorptions by cell nucleus from alpha particles and Auger electrons emitted by 211At have been calculated using a Monte Carlo calculation program (code: UNMOC). For these calculations two different model corresponding to the cell nucleus have been used and the data obtained were compared with the data earlier obtained for I25I. As a result, the radiotoxicity of 21lAt is in the competition with 125I. In the case of a specific agent labelled with 2I1At or 125I is incorporated into the cell or cell nucleus, but non-bound to DNA or not found very close to it, 2llAt should considerably be much more radiotoxic than i25I, but in the case of the labelled agent is bound to DNA or take a place very close to it, the radiotoxicity of i25I should considerably be higher than 21'At. 1. INTRODUCTION 21'At as an alpha and Auger emitter radionuclide has an extremely high potential application in cancer therapy; particularly, in molecular radiotherapy.

Of the Periodic Table
of the Periodic Table teacher notes Give your students a visual introduction to the families of the periodic table! This product includes eight mini- posters, one for each of the element families on the main group of the periodic table: Alkali Metals, Alkaline Earth Metals, Boron/Aluminum Group (Icosagens), Carbon Group (Crystallogens), Nitrogen Group (Pnictogens), Oxygen Group (Chalcogens), Halogens, and Noble Gases. The mini-posters give overview information about the family as well as a visual of where on the periodic table the family is located and a diagram of an atom of that family highlighting the number of valence electrons. Also included is the student packet, which is broken into the eight families and asks for specific information that students will find on the mini-posters. The students are also directed to color each family with a specific color on the blank graphic organizer at the end of their packet and they go to the fantastic interactive table at www.periodictable.com to learn even more about the elements in each family. Furthermore, there is a section for students to conduct their own research on the element of hydrogen, which does not belong to a family. When I use this activity, I print two of each mini-poster in color (pages 8 through 15 of this file), laminate them, and lay them on a big table. I have students work in partners to read about each family, one at a time, and complete that section of the student packet (pages 16 through 21 of this file). When they finish, they bring the mini-poster back to the table for another group to use.

A Note on Radioactive Materials and Their Measurements Elements Are
A NOTE ON RADIOACTIVE MATERIALS AND THEIR MEASUREMENTS Elements are placed in the periodic table of elements according to atomic number or proton number often referred to as Z. Their atomic weights are also usually indicated and can be fractional if the element in nature contains more than one isotope. Isotopes of an element all have the same atomic number, Z, but have different numbers of neu- trons. Some of these isotopes, even in naturally occurring elements, may be radioactive, and are usually given the atomic weight of the longest known isotope. Radioactive decay occurs when an unstable atom loses energy by emitting particles and gamma radiation or by spontaneously fission- ing. (Spontaneous fission is one of the natural modes of radioactive decay in which fission occurs without the addition of external energy or particles.) The activity of a radioactive sample is simply the rate of radioactive decay, expressed as the number of decays per unit time. Traditionally, the curie (Ci) was used to quantify the decay rate and was defined as the radioactivity measured for one gram of pure radium, or ~3.7 × 1010 decays per second (d/s), but the value changed as measurement techniques improved. To avoid this problem of a “chang- ing” constant, the Curie is now defined as exactly 3.7 × 1010 d/s. The becquerel (Bq), equal to one d/s, is the official SI unit (International System of Units). The roentgen R( ) is commonly used as a unit of radiation exposure to X-ray or gamma radiation, and can be roughly defined as “that quan- tity of X-ray or gamma radiation needed to produce one electrostatic unit of ionic charge in one cm3 of air under standard temperature and pressure (STP) “normal conditions”.

Periodic Table 1 Periodic Table
Periodic table 1 Periodic table This article is about the table used in chemistry. For other uses, see Periodic table (disambiguation). The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic numbers (numbers of protons in the nucleus), electron configurations , and recurring chemical properties. Elements are presented in order of increasing atomic number, which is typically listed with the chemical symbol in each box. The standard form of the table consists of a grid of elements laid out in 18 columns and 7 Standard 18-column form of the periodic table. For the color legend, see section Layout, rows, with a double row of elements under the larger table. below that. The table can also be deconstructed into four rectangular blocks: the s-block to the left, the p-block to the right, the d-block in the middle, and the f-block below that. The rows of the table are called periods; the columns are called groups, with some of these having names such as halogens or noble gases. Since, by definition, a periodic table incorporates recurring trends, any such table can be used to derive relationships between the properties of the elements and predict the properties of new, yet to be discovered or synthesized, elements. As a result, a periodic table—whether in the standard form or some other variant—provides a useful framework for analyzing chemical behavior, and such tables are widely used in chemistry and other sciences. Although precursors exist, Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table.
