The Periodic Table The periodic table of the chemical elements (also periodic table of the elements or just the periodic table) is a tabular display of the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869, who intended the table to illustrate recurring ("periodic") trends in the properties of the elements. The layout of the table has been refined and extended over time, as new elements have been discovered, and new theoretical models have been developed to explain chemical behavior. The periodic table is now ubiquitous within the academic discipline of chemistry, providing a useful framework to classify, systematize, and compare all of the many different forms of chemical behavior. The layout of the periodic table demonstrates recurring ("periodic") chemical properties. As of 2010, the table contains 118 chemical elements whose discoveries have been confirmed.

Physics Simulation with Java How to Make a Paper Airplane | Origami for Kids Spelling with Elements Special holliday shipping note: Order by Saturday, Dec 20th for delivery in time for x-mas (except PhotoGlows)! Ignore the 2-3 week shipping notes below, we will do a special last-minute run of everything ordered by the 20th. PhotoGlow banners must be ordered by Dec 15th for x-mas delivery and PhotoGlows over 48" wide cannot be delivered in time. Enter any string of letters and spaces below to see if it can be written in terms of chemical element abbreviations. Try your name, or the names of friends! If you're lucky with your word, name, or phrase, you can order it as a high-quality photographic banner custom-printed with an archival pigment ink printer on heavy-weight satin finish paper. NEW! If you can't find a way to spell what you want, you can always order a copy of my Photographic Periodic Table Poster, from which these images are taken.

Alkali metals:brainiac, open university and Francium clips Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.

Graphene Will Change the Way We Live | Dr. Kaku's Universe The theory behind the substance graphene was first explored by theoretical physicist Philip Wallace in 1947 as kind of a starting point when he was doing research trying to understand the electronic properties of more complex, 3D graphite. although the name graphene wasn't actually coined until 40 years later, where it was used to describe single sheets of graphite. In other words, it's the name given to a flat monolayer of carbon atoms that are tightly packed into a 2D honeycomb lattice; like a molecular chicken-wire that is one atom thick. It's essentially the basic building block for graphitic materials of all other dimensionalities; it's a stepping stone to building bigger things. Graphene in itself however wasn't discovered until 2004 in its full observable and testable form. Since then, in the past 6 years, scientists have discovered that the substance retains some amazing properties.

Energy Kids - Periodic Table File Scrub 1 ::::: EK ... periodic_table The periodic table is the most important reference a chemist has because it puts all the known elements into a meaningful pattern. Elements are arranged left to right and top to bottom in order of increasing atomic number. This order generally goes with increasing atomic mass. The different rows of elements are called periods. The period number of an element signifies the highest energy level an electron in that element occupies (in the unexcited state). Learn more about the periodic table and each of the elements on the Los Alamos National Laboratory website. Group 1 - The Alkali Metals

Secret Worlds: The Universe Within - Interactive Java Tutorial Secret Worlds: The Universe Within View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. Once the tutorial has completely downloaded, a set of the arrows will appear that allow the user to increase or decrease the view magnitude in Manual mode. Notice how each picture is actually an image of something that is 10 times bigger or smaller than the one preceding or following it. Earth = 12.76 x 10+6 = 12,760,000 meters wide (12.76 million meters) Plant Cell = 12.76 x 10-6 = 0.00001276 meters wide (12.76 millionths of a meter) Scientists examine things in particular ways using a combination of very sophisticated equipment, everyday instruments, and many unlikely tools. Note: - The sequence of images in this tutorial has been optimized for maximum visual impact. Contributing Authors

Build an Atom - Atomic Structure, Atoms, Atomic Nuclei Topics Atoms Atomic Structure Isotope Symbols Atomic Nuclei Description Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas! Sample Learning Goals Use the number of protons, neutrons, and electrons to draw a model of the atom, identify the element, and determine the mass and charge.Predict how addition or subtraction of a proton, neutron, or electron will change the element, the charge, and the mass.Use the element name, mass, and charge to determine the number of protons, neutrons, and electrons.Define proton, neutron, electron, atom, and ion.Generate an isotopic symbol for an atom, given the number of protons, neutrons, and electrons.

Mixtures and compounds Transit Agencies We’ve been following the trend of transit agencies providing developer access to timetables, routes and more for some time. Big cities, like New York and Boston are on board and helping fuel new transit applications. There now seems to be more momentum, with organizations and influencers making the call for open data. StreetFilms talked to some of these people, several within transit companies themselves, and created A Case for Open Data (embedded below). “If you take the model of the national weather service and apply it to the transit agencies you realize you can have just as many ways to get transit information as you do to get weather information. When we profiled the developer who is trying to open transit data earlier this year, City-Go-Round showed 91 agencies with public data. But it’s a good sign when big metros get behind open transit data. via Jehiah Both comments and pings are currently closed.
