    You can download the 26 MB Powerpoint presentation for that talk; it will have all his slides, and the comment box will have his monologue regarding each slide. How to get acquainted with the new table If you haven't had luck with the on-line presentation or version with pop-ups just above. The best way to start with the table is to go to the legend at top center. It shows that there are many small colored symbols for natural occurrences of ions. Then go to the left side of the table, to the block labeled "Hard or Type A Cations". In this block, you should see that those symbols fall in blue-and-green, red-and-brown, and blue-and-green swaths. You're seeing the main strength of this new table: natural occurrences of ions fall in predictable patterns across this table, whereas the conventional table doesn't make much sense of natural occurrences. That new arrangement is what lets the swaths of color emerge. If you now go to the right, to "intermediate cations" and onward over to the anions, you'll see the table's second and even more fundamental change from conventional tables: some elements appear multiple times. That's because they take on multiple charges in nature, and behave very differently in those different conditions. If you now look at the entire table, or at least the left and middle the blocks hard and intermediate cations , you'll see the colored symbols fall in swaths across the table. Those swaths follow some colored curving lines.

    Hydrogen is prepared by steam on heated carbon,l decomposition of certain hydrocarbons with heat,l action of sodium or potassium hydroxide on aluminuml electrolysis of water, orl displacement from acids by certain metals. Hydrogen is the primary component of Jupiter and the other gas giant planets At some depth in the Tritium is readily produced in nuclear reactors and is used in the production of the hydrogen bomb.

    In , a group of Russian experimenters may have produced metallic hydrogen at a pressure of 2. At the transition the density changed from 1.

    Earlier, in , at Livermore, California, a group also reported on a similar experiment in which they observed a pressure-volume point centered at 2 Mbar. Predictions say that metallic hydrogen may be metastable; others have predicted it would be a superconductor at room temperature. Although pure Hydrogen is a gas we find very little of it in our atmosphere Hydrogen gas is so light quickly be ejected from the atmosphere On earth, hydrogen occurs chiefly in combination with oxygen Compounds that uncombined Hydrogen will gain enough velocity from collisions with other gases that they will in water, but it is also present in organic matter such as living plants, petroleum, coal, etc.

    It is present as the free element in the atmosphere, but only to the extent of less than 1 ppm by volume. The lightest of all gases, hydrogen combines with other elements -- sometimes explosively -- to form compounds.

    Uses Great quantities are required commercially for the fixation of nitrogen from the air in the Haber ammonia process and for the hydrogenation of fats and oils. It is also used in large quantities in methanol production, in hydrodealkylation, hydrocracking, and hydrodesulfurization.

    Other uses include rocket fuel, welding, producing hydrochloric acid, reducing metallic ores, and filling balloons. The lifting power of 1 cubic foot of hydrogen gas is about 0.

    The Hydrogen Fuel cell is a developing technology that will allow great amounts of electrical power to be obtained using a source of hyrogen gas.

    Public acceptance, high capital investment, and the high cost of hydrogen with respect to today's fuels are electrolyze seawater; the hydrogen produced would travel to distant cities by pipelines.

    Pollution-free hydrogen could replace natural gas, gasoline, etc. For users needing an atomic-weight value for an unspecified sample with disregard to the uncertainty, the conventional values are provided.

    No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural terrestrial samples. Holden, Tyler B. By virtue of its work in relation with the chemical elements, IUPAC can dispense a periodic table that is up-to-date.

    Periodic Table of Elements

    IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input. The table is yours to use. Details about the latest release are provided above. Criteria and guidelines for establishing priority of discovery of potential new elements are presented.

    While an element can have been claimed, before the claim has been validated and before the element is formally named, the element has a temporary name and symbol. Claims for the discoveries of new elements appear time to time in the scientific literature. In result, IUPAC technical reports are released that review each pertaining references and recognize the laboratory ies whose claims fulfill the agreed criteria.
