Database of Periodic Tables

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.

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.

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

Periodic Table Battleship I have posted a lot about Chemistry lately. My oldest has been studying it and really enjoying it. I love his science-y mind! This game can be played even by kids who know nothing about the Periodic Table Yet. To make the game, print out 4 copies of the Periodic Table. The kids can then mark where they want to place their ships by circling rows of 2, 3, 4, and 5 elements on the lower table.. ** I used coordinates because my 8-year-old was scared of trying to read all of the elements, but after they got going they were just calling out elements names instead of the letters and numbers. By reader request, we made a video of how to play! Also, Buy a physical copy of the game! Like this post? I also made some Chemical Compound Flash Cards you can purchase in my shop.
