Database of Periodic Tables
There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach. Harrington Periodic Tables So we start this effort tabula rasa (without preconceived ideas). 1) All atoms have a default "common denominator" structure at 270 mass units, irrespective of the element under discussion. Top of Page KAS Periodic Table The KAS periodic table reproduces and depicts the nuclear properties of chemical elements. The Segre Chart is based on the number of protons, Z, and the number of neutrons, N. Location that remains near the Neutron Dripline of element. Read more here, here and here.

Periodic Tables providing data about the chemical elements, rather than novel formulations: Theo Gray's Photographic Periodic Table Theodore Gray's Periodic Table.Com is a live version of what is generally regarded as the most beautiful periodic table to be developed so far. Theo is an enthusiast and a collector, and he uses the power of Mathematica (he is a co-founder of Wolfram Research) to drive his astonishing website. Top of Page WebElements: The Periodic Table on The Web As of Dec. 2012, there are 118 chemical elements, according to the excellent webelements periodic table web site: The number of known elements does change. 94 Elements: The Stuff of Everything The stories of the elements are the stories of our own lives.

De quoi la planète Terre est-elle composée ? L’élément le plus abondant dans l’Univers est l’hydrogène, suivi de l’hélium, les deux éléments les plus simples au niveau atomique et les plus légers de tous. Du moins c’est ce que l’on constate en scrutant l’Univers. Car même si aujourd’hui, avec les dernières générations de télescopes, on voit très, très loin, les spécialistes estiment que l’on ne distingue que 10 % de la matière de l’Univers. Pour ce qui est de la matière visible, elle est composée de 90 % d’hydrogène, de 9 % d’hélium, d’un fifrelin (0,1 %) d’oxygène ou encore d’un soupçon (0,06 %) de carbone. Mais redescendons dans notre univers, la Terre. Il y a dans cette liste des absents de marque. Il y a également ce que l’on pourrait appeler des «intrus». Quelques surprises L’histoire réserve elle aussi quelques surprises. Il y a pourtant bien des métaux rares et même très rares. Mais l’or n’est pas l’élément le plus rare. Dernière chose. Par J.L.

Spray-on liquid glass is about to revolutionize almost everything ( -- Spray-on liquid glass is transparent, non-toxic, and can protect virtually any surface against almost any damage from hazards such as water, UV radiation, dirt, heat, and bacterial infections. The coating is also flexible and breathable, which makes it suitable for use on an enormous array of products. The liquid glass spray (technically termed “SiO2 ultra-thin layering”) consists of almost pure silicon dioxide (silica, the normal compound in glass) extracted from quartz sand. Liquid glass was invented in Turkey and the patent is held by Nanopool, a family-owned German company. The liquid glass spray produces a water-resistant coating only around 100 nanometers (15-30 molecules) thick. Food processing companies in Germany have already carried out trials of the spray, and found sterile surfaces that usually needed to be cleaned with strong bleach to keep them sterile needed only a hot water rinse if they were coated with liquid glass.

17 Science Experiments That Will Make Childhood Unforgettable We care for our children every day. But in 20 years it won't be the everyday tasks we performed for them that they'll remember. Instead, it will be the moments we spent together. Bright Side put together a selection of the 16 best science experiments that will both tear you away from your concerns and fascinate your children. Hard liquid You will need: Starch Water A plastic container Food coloring, a wooden board, a hammer, and some nails for additional experimentation Mix the water and the starch together in the container until the mixture turns viscous in its consistency. Homemade kinetic sand 4 teaspoons of boric acid 2 teaspoons of ordinary paper glue 1 teaspoon of coloring 100 g of chinchilla bathing sand A glass bowl Pour all the liquid components into a bowl, add the sand, and thoroughly mix them together. Glowing water 2-3 highlighters Pliers A measuring cup Tweezers A UV Light Pour water into a few glasses (2-3 in number), filling them about 2/3 of the way. Making a Pharaoh snake

UPDATE #2: NEW! Periodic Table of Criminal Elements | PlanetPOV I need your help because my ideas are drying up. This is what I have so far and I’ve thought of about a dozen more to add that I can think of including the SCOTUS judges, and usual rabble of right wing talking heads. I need help identifying the lying and corrupt politicians, blowhards and business execs that destroy America. I was browsing some old pictures to download to my phone and I came across one of the funniest and most poignant images I came across during the election. Periodic Table of Criminal Elements To satisfy my scientific post of the week as well following this paragraph are a few interesting versions of the periodic table. Most Up to Date Traditional Configuration of the Periodic Table of Elements (PTOE) Traditional PTOE with Pictures of the Elements in Their Native Form.
