		naming elements ^Votes:0 Ask A Scientist © Physics Archive Naming Elements Question: How do you name elements and how are they identified? Answer: Actually, this is more of a "chemistry" question... The elements that occur naturally were all discovered a long time ago, so the problem of naming them does not come up anymore - they already have names. However, there are some official international organizations (IUPAP/IUPAC I think?) that are responsible for establishing the names used in scientific work, not only for the elements but also for new molecules etc. The standard way in which elements are given names is that the discoverer is allowed to pick a name - this has resulted in debates between groups in the U.S. and Russia over who actually discovered the latest heavy elements first. There are several ways to i Read More Go to Site

		C&EN: The Periodic Table--1923 & 1998 ^Votes:0 Chemical & Engineering News January 12, 1998 Copyright © 1998 by the American Chemical Society Rebeccca L. Rawls C&EN Washington T he past 75 years have been some of the richest ever for the discovery of new elements. Since C&EN began publication in 1923, 26 elements have been added to the periodic table. On average, that's about one new element every three years. 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 reac Read More Go to Site

		E007: The Masurium File: An X-Ray Mystery ^Votes:0 E007 The Masurium File: An X-Ray Mystery. David H. Templeton, Department of Chemistry, University of California, Berkeley, CA 94720-1460. Walter Noddack, Ida Tacke and Otto Berg [1] reported the discovery of masurium and rhenium, elements 43 and 75, on the basis of weak lines in X-ray spectra excited by electron impact on fractions extracted from niobium and platinum ores. Some or all of these ores contained uranium. Further work produced larger amounts of Re, and it became an item of commerce, but Ma was not detected again. Perrier and Segre [2] are now credited with finding technetium, element 43, as radioactive isotopes made in a cyclotron. Several conjectures may explain how Ma was first observed and then not found again, or else how the authors deceived themselves. It is now known tha Read More Go to Site

		embalming ^Votes:0 home John L. Konefes and Michael K. McGee Old Cemeteries, Arsenic, and Health Safety [click Water Industry News , Water Facts when you arrive] E mbalming human remains for burial has taken a long road to its present state as an art that now minimizes health and environmental concerns of burials. Along the way, health and safety were not always considerations. From the Civil War until about 1910, arsenic was the main ingredient in the embalming fluids used widely throughout the country. Although effective, arsenic is toxic and persistent, and elemental arsenic will never degrade into harmless by- products. Progress in embalming practices during the late 1880s has left a legacy that can potentially harm the health of archeologists or cemetery workers, and impact the environment.

		newelements ^Votes:0 The triumph of Mendeleev's work lay in the ability to predict the existence of elements then unknown.

The selection below is from his paper in the Journal of the Russian Chemical Society, 3: 25-56 (1871), which performs the same function for eka-boron.

In rocks of the Earth's crust generally, at up to 4 ppm, and incorporated into many minerals. In ore, as uraninite (UO 2 ) or pitchblende (U 3 O 8 ) or as secondary minerals (complex oxides, silicates, phosphates, vanadates). Australian ores are up to O.5% U 3 O 8 , in Canada they range up to 25% U 3 O 8 . U 3 O 8 is a stable complex oxide: U 2 O 5 .UO 3 . Uranium is fairly soluble and uranium oxide precipitates from uranium-bearing groundwaters as they enter a reducing environment. It can be mobilised (redissolved) in situ by oxygenated leach solution. Extraction from ore, at the mine The ore is crushed and ground to liberate the mineral particles.

		Tim's Rocks ^Votes:0 ROCKS!! All righty, time for a little bit on minerals. This section I'm pretty shaky on, so all I can do is try. First off, there's a difference between MINERALS and ELEMENTS . Elements are those things on the Periodic Table, you know, with the atomic numbers and all? Well, minerals are different. They're really a bunch of elements put together to make some kind of structure, like rocks. There are two main properties that are associated with minerals, and those are composition and texture. Composition refers to what the thing's made out of, especially when you're talking chemistry. It's like what elements go into making it what it is. Now, texture, on the other hand, is what it looks like. Color , size , shape of grains, relative abundance, and yes, even taste, all make up the physical pro Read More Go to Site

		Tungsten Properties ^Votes:0 Properties of Tungsten Background Information The word tungsten means "heavy stone" in Swedish. The chemical symbol for tungsten is W which stands for wolfram. The name came from medieval German smelters who found that tin ores containing tungsten had a much lower yield. It was said that the tungsten devoured the tin "like a wolf". Pure tungsten metal was first isolated by two Spanish chemists, the de Elhujar brothers in 1783. Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids. Detailed history Information o Read More Go to Site

		Unit 4: Section 2 ^Votes:0 U nit 4: Up Close: The Periodic Table of Elements S ection 2: Transition Metals Introduction Properties of Transition Metals Some Transition Metals I ntroduction When you stare at the perodic table, you see nice whole columns of elements that are grouped together with similar properties. After group 1 and group 2, you see a big gap before you reach group 3. As you peer harder at this gap, you see elements in between group two and group three. These are the transition elements. In this section, we shall touch up on the properties of some of these elements. P roperties of Transition Metals The transition metals, also known as the transition elements, occupy the space between group 2 and group 3 of the perodic table. Metals such as gold, silver, copper, iron, nickel, chromium, and mercury are Read More Go to Site

In order to maximize speed and compatibility with various graphical web browsers, I have largely limited myself to the 216 colors used by Netscape running under Windows with 8 bit video. 125 of these colors have nonzero use of all three primaries, about 12-15 are obviously non-spectral magentas and purples, and and a few others are questionable purplish colors. That leaves only about 75 colors to use, including bright and dark shades. In addition, the color phosphors used in computer monitors are not capable of accur Read More Go to Site
