Periodic Table: virtual reactions
Interactive Features | More Science Whether gas, liquid or solid; radioactive or stable; reactive or inert; toxic or in your vitamin pill, the 118 building blocks each has its own chemically idiosyncratic characteristics--and certain commonalities. See what makes your favorite element unique on this interactive periodic table By Davide Castelvecchi | June 18, 2013 | In the October 2011 issue of Scientific American, we celebrate the International Year of Chemistry. Learn more about its impact on our daily lives in our Special Report.
The periodic table is a table of the chemical elements in which the elements are arranged by order of atomic number in such a way that the periodic properties (chemical periodicity) of the elements are made clear. The standard form of the table includes periods (usually horizontal in the periodic table) and groups (usually vertical). Elements in groups have some similar properties to each other. There is no one single or best structure for the periodic table but by whatever consensus there is, the form used here is very useful.
Explore Shale geology, water, gas, oil Why is water used in fracking? In order to extract natural gas from low permeability shale, fracturing fluids are pumped into a wellbore, a process which increases pressure underground, causes shale layers to crack, and allows the gas contained within the shale to escape. Water is accessible, affordable, and incompressible so it is the primary component of fracking fluid. How much water is used? Each drill site requires between 3 and 5 million gallons of water per frack.
Heating Plastics Lists of Nobel Prizes and Laureates Plastics Play the Heating Plastics Game About the game There are two major groups of plastics - some melt when heated and others don't.

Molecular Workbench offers interactive, visual simulations and activities that have been widely used in science teaching for students of all ages. Our database is designed to provide teachers and students with easy access to our model-based activities. The activities are derived largely, but not entirely, from projects of the Concord Consortium sponsored by the National Science Foundation (NSF).
Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one. We've done all 118 - but our job's not finished. Now we're updating all the videos with new stories, better samples and bigger experiments. Plus we're making films about other areas of chemistry, latest news and occasional adventures away from the lab. We've also started a new series - The Molecular Videos - featuring our favourite molecules and compounds.
