Periodic table - Elements, Groups, Blocks: The periodic table of the elements contains all of the chemical elements that have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthano

Note:Elements in PicturesandElements in Wordsare a set. Either may stand alone, but they work best together. . This contains most of the same information on an interactive web page. This textual periodic table is packed with even more information. In addition to the element's name, symbol,...
History of the Periodic table of elements - Short history of how the Periodic table of chemical elements was arranged, from Lavoisier's Table of simple substances to Seaborg Actinide concept.

The history of the development of the periodic table of elements 1.The Beginnings of the Periodic Table ? Before written history, people were aware of some of the elements in the periodic table. Elements such as gold (Au), silver (Ag), copper (Cu), lead (Pb), tin (Sn), and mercury...
Table 1.Lavoisier's table of simple substances The English chemist John Dalton (1766-1844) proposed his principles of atomic theory in 1803, suggesting that all elements are composed of tiny, indestructible particles called atoms, all of which are equal and weigh exactly the same. Atoms belonging...

That’s whythis periodic table clockreally caught our eye. [gocivici]’s idea is a simple one: light up three different elements with three different colors for hours, minutes, and seconds, and read off the time using the atomic number of the elements. So, if it’s 13:03:23, that ...
