The Photographic Periodic Table The definitive online periodic table reference site including technical data, and photographs and descriptions of thousands of samples of the chemical elements.	Visual Elements Periodic Table The Royal Society of Chemistry's interactive periodic table features history, alchemy, podcasts, videos, and data trends across the periodic table.	Dynamic Periodic Table Interactive periodic table with dynamic layouts showing names, electrons, oxidation, trend visualization, orbitals, isotopes and more ...
Interactives - The Periodic Table The periodic table kind of looks like a mess of random letters and numbers, right? Well it's actually one of the most important tools for understanding chemistry!	Photo of a Single Atom You might need your glasses for this one. Quantum physicist David Nadlinger from the University of Oxford managed to capture an image that would have been impossible only a few years ago: a single atom suspended in an electric field viewable by the naked eye. The amazing shot titled “Single Atom in an Ion Trap” recently won the overall prize in the UK’s Engineering and Physical Sciences Research Council (EPSRC) science photo and imaging contest.	ABCs of Particle Physics Take an interactive animated journey through the particle physics alphabet. Inspired by children’s books, we’ve pulled 26 of our favorite particle physics concepts into a short, rhyming collection for folks of all ages. You’ve heard “A is for apple,” but here at Symmetry, A is also for accelerator.
Chem4Kids Information on matter, atoms, elements, the periodic table, reactions, and biochemistry.	The Energy in Chemical Bonds Suppose I take some hydrogen gas and mix it with oxygen gas. What happens? Nothing. Nothing happens unless you add a bit of energy—from a spark, perhaps. Add energy and BOOM: You get an explosion, and the hydrogen and oxygen (some of it) make water. Clearly this reaction releases energy, but where did the energy come from?	Periodic Videos Your ultimate channel for all things chemistry. A video about each element on the periodic table. And we upload new videos every week about science news, interesting molecules and other stuff from the world of chemistry.
Where Does the Periodic Table End? Scientists keep finding new pure units of matter — but it's getting ever harder.	Beautiful Chemistry Explore some of the most beautiful chemical structures and reactions.	Materials Science Discovery Channel Articles, images and videos.
IUPAC International Union of Pure and Applied Chemistry. The International Union of Pure and Applied Chemistry (IUPAC) serves to advance the worldwide aspects of the chemical sciences and to contribute to the application of chemistry in the service of Humankind. As a scientific, international, non-governmental and objective body, IUPAC can address many global issues involving the chemical sciences.	The Path to the Periodic Table The path to the periodic table began early in the 19th century, when John Dalton united the atomic theory of matter, which had existed in various forms since antiquity, with the concept of the chemical element, which had emerged in the late 18th century with the work of Antoine-Laurent Lavoisier and his followers.	Antoine-Laurent Lavoisier Lavoisier, a meticulous experimenter, revolutionized chemistry by establishing the law of conservation of mass, determining that combustion and respiration are caused by chemical reactions with what he named "oxygen," and helping systematize chemical nomenclature, among many other accomplishments.
Julius Meyer and Dmitri Mendeleev For both Julius Meyer and Dmitri Mendeleev, writing a textbook proved to be the impetus for developing the periodic table—a device to present the more than 60 elements known at the time in an intelligible fashion.	Glenn Theodore Seaborg Glenn Seaborg was involved in identifying nine transuranium elements and served as chairman of the U.S. Atomic Energy Commission from 1961 to 1971. In 1951 he received the Nobel Prize in Chemistry.	Chernobyl the catastrophe that ... Nearly 30 years after the explosion, Bob Simon travels to Ukraine and discovers the reactor still has the power to kill.
The First Image of a Hydrogen Bond Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond.	Compound Interest Everyday exploration of chemical compounds.	iPad App Oresome Elements Oresome Elements is an interactive game that makes learning about the periodic table, elements and some of their properties and uses fun.
iPad App Periodic Table This fact-filled, image-rich app is the only periodic table you need. By Royal Society of Chemistry.	iPad App Nova Elements Did you ever wonder why the periodic table is shaped the way it is, what gives each element its own unique set of properties, or even how elements combine to make everyday objects such as a cup of coffee? With “NOVA Elements,” explore an interactive periodic table, play a game hosted by David Pogue, or watch the two-hour NOVA program, “Hunting the Elements.”	iPad App Atoms HD With the Building Atoms, Ions, and Isotopes app, explore the composition of the elements. Build atoms, ions, and isotopes by selecting appropriate numbers of protons, neutrons, and electrons. For reference, this app also includes atomic theory information and a periodic table that is interactive in the iPad version.
iPad App Chemio Interactive periodic table, solubility table, molar mass calculator and the 3D widget for designing electron configuration of atom.	iPad App goREACT With goREACT, you can become a virtual chemist. Whether you're a novice or expert, the free play and guided modes make it fun and fascinating.	iPad App Nuclear Dare you enter the quantum world of Nuclear? Where things are not just stranger than you might imagine, but stranger than you can imagine! Witness the interplay of energies and physics at the tiniest of scales as you learn to play, discover and explore the chemical elements at the atomic level.
