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.
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?

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.
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.
