Many other interactive periodic tables are available on the web; you can learn more about elements in the Periodic Table in the Visual Elements table from the Royal Society of Chemistry and this photographic one. pdboyer Mon, 23 May 2011 00:23:37 GMT http://www.youtube.com/results?suggested_categories=27%2C24%2C22&search_query=its+elemental%2C+channel its elemental, channel pdboyer Sun, 15 May 2011 17:59:59 GMT http://www.periodicvideos.com Interactive Whiteboard pdboyer Wed, 11 Feb 2009 03:53:37 GMT http://science.nasa.gov/astrophysics/big-questions/when-and-how-did-the-elements-of-life-in-the-universe-arise/ Following the Big Bang and the gradual cooling of the Universe, the primary constituents of the cosmos were the elements hydrogen and helium. Even today, these two elements make up 98% of the visible matter in the Universe.  Nevertheless, our world and everything it contains—even life itself—is possible only because of the existence of heavier elements such as carbon, nitrogen, oxygen, silicon, iron, and many, many others. How long did it take the first generations of stars to seed our Universe with the heavy elements we see on Earth today?  When in the history of the Universe was there a sufficient supply of heavy elements to allow the formation of prebiotic molecules and terrestrial-like planets pdboyer Sat, 06 Nov 2010 19:38:23 GMT
