Description: All our Minerals are 100% Genuine Specimens & come with a Certificate of Authenticity Specimen: Silicon Type: Mineral/Crystal Scale cube=1cm: Full sizing please see photo Silicon is a chemical element with symbol Si and atomic number 14. It is also a semiconductor, meaning that it does conduct electricity though, unlike a typical metal, silicon gets better at conducting electricity as the temperature increases (metals get worse at conductivity at higher temperatures). Silicon makes up 27.7% of the Earth's crust by mass and is the second most abundant element (oxygen is the first). It does not occur uncombined in nature but occurs chiefly as the oxide (silica) and as silicate minerals, these minerals account for 90% of the Earth's crust. Elemental silicon is produced commercially by reducing sand with carbon in an electric furnace. ACTUAL AS SEEN: The image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.
