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.

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: StarchWaterA plastic containerFood 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 acid2 teaspoons of ordinary paper glue1 teaspoon of coloring100 g of chinchilla bathing sandA 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 Smoke rings

AP Chemistry Review Activities AP Chemistry Interactive Review Activities In keeping with the new framework for AP Chemistry beginning in 2013 - 2014, I am indicating here if the topic to which a review activity relates has been dropped from the curriculum. It will be identified as excluded (Excluded) to indicate that the College Board has specifically excluded it. I will leave the reviews here, however, in case some of you find them useful. These are not graded assignments. They are intended only as practice of concepts and vocabulary that are essential to your success in this course. Each time you reload the activity, the problems will be in a different order, and the answers will be reshuffled!

This is the placebo effect: somehow, sometimes, a whole lot of nothing can be very powerful. So what is going on? Benedetti has since shown that a saline placebo can also reduce tremors and muscle stiffness in people with Parkinson's disease. We have a lot to learn about what is happening here, Benedetti says, but one thing is clear: the mind can affect the body's biochemistry. 2 The horizon problem OUR universe appears to be unfathomably uniform. Nothing can travel faster than the speed of light, so there is no way heat radiation could have travelled between the two horizons to even out the hot and cold spots created in the big bang and leave the thermal equilibrium we see now. This "horizon problem" is a big headache for cosmologists, so big that they have come up with some pretty wild solutions. 3 Ultra-energetic cosmic rays More from the web

Chemicum - 100+ Experiments in Chemistry II Periodic Table of Elements and Chemistry Design4Resilience | Get "fit for randomness" [with Ontonix UK] The trend to articulate product offering is putting pressure on manufacturing companies like never before. Therefore, the complexity of modern products and of the associated manufacturing processes is rapidly increasing. High complexity, as we know, is a prelude to vulnerability. It is a fact that in all spheres of social life excessive complexity leads to inherently fragile situations. Complexity X Uncertainty = Fragility read more… White Paper 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.
