  • 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.

  • Attachment 2
    Solving Important Problems with Thorium Reactors Kirk Sorensen Flibe Energy March 2, 2016 Our industrial civilization expects reliable, affordable energy. The energies that bind the atomic nucleus (nuclear energy) are approximately two million times greater than the energies that bind the atomic electrons (chemical energy). Three Nuclear Options Possible Nuclear Fuels Natural Thorium Natural Uranium 100% thorium-232 99.3% uranium-238 0.7% uranium-235 Only a small fraction of natural uranium is fissile. Most uranium and all thorium is "fertile" and can be converted to fissile material through neutron absorption. Reducing Long-Lived Waste I Today’s approach to nuclear energy consumes only a small amount of the energy content of uranium while producing "transuranic" nuclides that complicate long-term waste disposal. I Using thorium/U-233 in a liquid-fueled reactor can more nearly approach the ideal of a fission-product-only waste stream that reaches the same radioactivity as uranium ore in 300 years. Today’s nuclear fuel is fabricated with extraordinary precision, like a fine watch. But it is that precision that makes it difficult to recycle and to refabricate. A new approach is needed that is more versatile and less expensive. Fluoride salts are safe and versatile Chemically stable in air and water Unpressurized liquid with 1000◦C range of temperature LiF-BeF2 fluoride salt is an excellent carrier for uranium (UF4) nuclear fuel. Liquid fuels enhance safety options The reactor is equipped with a "freeze plug"—an open line where a frozen plug of salt is blocking the flow. The plug is kept frozen by an external cooling fan.

  • (Lead-Tin-Bismuth-Cadmium) Having Low Melting Temperature
    VAEC-AR 07--37 STUDY ON TECHNOLOGY FOR MANUFACTURING ALLOY (LEAD - TIN - BISMUTH - CADMIUM) HAVING LOW MELTING TEMPERATURE (≤ 800C) USED TO SHIELD RADIOACTIVE RAYS FOR TREATING CANCER Ngo Xuan Hung, Pham Duc Thai, Nguyen The Khanh Vu Quang Chat and Nguyen Huu Quyet Institute for Technology of Radioactive and Rare Elements, VAEC, Vietnam. ABSTRACT: Up to now, hospitals in Vietnam have mostly imported radioactive equipments from America, German, France, England to treat cancer. Accompany with those equipments, alloy, namely Cyroben having low melting temperature (≤ 800C) is used to cover patients’ good tissues in order to protect them against harmful rays and help radioactive rays get through the cast hole to kill cancer cells. This project is carried out for determining chemical compositions and melting temperatures of researched alloy to create alloy having low melting temperature (≤ 800C) to meet demand for treating cancer in Vietnam. Key words: Processing flow sheet, name element: Lead (Pb); Tin (Sn); Bismuth (Bi); Cadmium (Cd). INTRODUCTION The Cyroben alloy (Pb – Sn – Bi – Cd) used to cover the cancer has to meet 3 basic demands: - Meet technique characters of radioactive treating: can cover 92-95% of radioactive rays (compared with open radiation source) in order to keep those harmful rays out of patients’ good tissues as few as possible. - Have low melting temperature (≤ 800C), easy to melt and to cast in complex shapes. - Prevent workers, patients and doctors from harmful rays. EXPERIMENT RESULTS AND DISCUSSION After analyzing chemical compositions, measuring melting temperatures of imported alloy samples, we have received following technique parameters. We have used these parameters as well as studied foreign reference documents for carrying out experiments.

  • Thorium and MSR Fuel Strategies Kirk Sorensen
    Thorium and MSR Fuel Strategies Kirk Sorensen, Flibe Energy Oak Ridge National Laboratory October 5, 2016 The production of long-lived nuclear waste has been a potent focus of opposition to nuclear power for many years. Because of the failure of the US government to take custody of spent nuclear fuel, it remains at the same site at which it was produced. This was once the site of the Connecticut Yankee reactor. Even after a nuclear power plant site has been decommissioned, the "orphaned" spent nuclear fuel remains on site in casks. These spent fuel casks cannot legally be moved from the decommissioned reactor site and prevent its release for unlimited use. They also require continuous security. For millions of people each year, receiving a diagnosis of cancer is a terrifying moment that leads to profound uncertainty. Targeted therapies look very promising against cancer, especially against dispersed cancers like leukemia and lymphoma. They seek out cancer cells, destroying them with chemicals or radiation while leaving healthy cells alone. Targeted Alpha Therapy using Bismuth-213 Bismuth-213 has a 45-minute half-life (perfect) and decays from actinium-225, which has a 10-day half-life (perfect). It is near the end of its decay chain, and can be suitably chelated (wrapped in a chemical cage) and attached to an antibody that will hunt down and attach to a bloodborne cancer cell. When it decays, the alpha particle it emits will kill the cancer cell. This is called targeted alpha therapy (TAT).

  • Properties of Lead-Bismuth, Lead-Tin, Type Metal, and Fusible Alloys
    RP248 PROPERTIES OF LEAD-BISMUTH, LEAD-TIN, TYPE METAL, AND FUSIBLE ALLOYS By J. G. Thompson ABSTRACT The tensile strength, hardness, and elongation of a number of lead alloys have been determined and are presented herewith. Data on the solidification charac- teristics and on the resistance to compression of some of the alloys also are presented. The alloys studied are divided into four classes: (1) Binary alloys of lead and bismuth, (2) binary alloys of lead and tin, (3) type metals, with and without the addition of small amounts of bismuth, and (4) fusible alloys of bismuth, lead, tin, and cadmium. The data are presented both in tabular form and in graphs. CONTENTS Page I. Introduction 1085 II. Lead-bismuth alloys 1086 1. Methods of test 1087 2. Discussion of results 1087 3. Summary 1090 III.

  • Bismuth Crystals RM-520
    Bismuth Crystals RM-520 What is Bismuth? Bismuth is a very unusual and rare metal that is solid at room temperature. It is more rare than platinum, ranking number 69 out of the 75 listed rare elements found on Earth's crust. One very interesting thing about bismuth is that its liquid form is denser than its solid form. So as bismuth crystallizes, its solid form floats above the liquid. This effect is only found in three other cases: water gallium germanium Bismuth crystals are man-made or man ‘grown.’ Their growing time is between 5-10 minutes after forming in a supercooled bismuth melt. In its solid form, bismuth is incredibly fragile. However, the crystals form to show perfect cleavage, making it tempting to handle and touch them. The reason the crystal structure is so fragile is because the rapid growth causes hollow forms, called ‘hopper crystals.’ The iridescent coloring is due to a thin layer of bismuth oxide that forms on the surface of the crystal as it cools. This is actually interference coloring, similar to the coloring you see on soap bubbles and on oil slicks, and is based on how thick the oxide grows. The brightness and color intensity can vary from sample to sample, depending on the quality and purity of the bismuth used. Activity Ideas: Gather at least five minerals with clear crystalline structures—i.e., calcite, pyrite, salt, etc. Have students study and sketch each mineral. Grow your own crystals!
