Periodic Table: Periodic Tables

SAN FRANCISCO (AP) -- Glenn Seaborg, the Nobel Prize-winning nuclear chemist who discovered plutonium and so many other elements that scientists had to redesign the periodic table, has died. He was 86.

The elements classified as "Rare Earth Elements" are located in Group 3 elements of the Periodic Table and in the 6th and 7th periods. The Rare Earth Elements are of the Lanthanide and Actinide series. Most of the elements in the Actinide series are synthetic or man-made. The Lanthanide and Actinide series of Rare Earth Elements are:

As you probably saw, the periodic table is organized like a big grid. The elements are placed in specific places because of the way they look and act. If you have ever looked at a grid, you know that there are rows (left to right) and columns (up and down). The periodic table has rows and columns, too, and they each mean something different.

The periodic table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize and compare all the many different forms of chemical behavior. The table has ... found wide application in physics, biology, engineering, and industry. The current standard table contains 117 confirmed elements as of January 27, 2008 (while element 118 has been synthesized, element 117 has not).

The element silicon is so closely identified with computers that most people would be likely to associate it more readily with California's high-tech valley than with the periodic table. But such thinking may soon have to be radically revised, as high-speed computation moves beyond chips and machines to include the tools of biochemistry and genetics: test tubes, slides, solutions--even DNA.

"The world and ourselves are built out of millions of connections all made from the same components, these same elements can all be found within the periodic table", explains co-founder Philipp. "We want to do the same with the Internet."
