The Gilbert U-238 Atomic Energy Laboratory was packaged in a customized metal case. The Gilbert U-238 Atomic Energy Lab is a toy lab set designed to allow children to create and watch nuclear and chemical reactions using radioactive material. The Atomic Energy Lab was released by the A. C. Gilbert Company in 1950.
The collection includes videos, each just a few minutes long, for all 118 known elements with a video for each element, as well as many additional supplemental chemistry videos. The 118 element videos and introduction videos were all shot unscripted in June and July 2008. [5] Since the initial videos were completed in 2008 the team has been ...
While at first the chemical garden may appear to be primarily a toy, some serious work has been done on the subject. [3] For instance, this chemistry is related to the setting of Portland cement, the formation of hydrothermal vents, and during the corrosion of steel surfaces on which insoluble tubes can be formed.
The experiment uses a conductive metal container A open at the top, insulated from the ground. Faraday employed a 7 in. diameter by 10.5 in. tall pewter pail on a wooden stool,(B) [ 1 ] but modern demonstrations often use a hollow metal sphere with a hole in the top, [ 10 ] or a cylinder of metal screen, [ 9 ] [ 12 ] mounted on an insulating stand.
For the metal foil, they tested a variety of metals, but favoured gold because they could make the foil very thin, as gold is the most malleable metal. [ 16 ] : 127 As a source of alpha particles, Rutherford's substance of choice was radium , which is thousands of times more radioactive than uranium.
A set of periodic-table elements, lacking several highly radioactive elements which are impractical or impossible to collect. An assortment of precious metals Hafnium samples for collectors. Element collecting is the hobby of collecting the chemical elements. Many element collectors simply enjoy finding peculiar uses of chemical elements.
Sieve elements are specialized cells that are important for the function of phloem, which is a highly organized tissue that transports organic compounds made during photosynthesis. Sieve elements are the major conducting cells in phloem. Conducting cells aid in transport of molecules especially for long-distance signaling.
A metalloid is a chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals.The word metalloid comes from the Latin metallum ("metal") and the Greek oeides ("resembling in form or appearance"). [1]
