49. Why Every English Classroom Should Have A Periodic Table? Thoreau and Emerson, both transcendentalists, stressed the interrelatedness of all things. http://www.chemistrycoach.com/whyevery.htm

Why Every English Classroom Should Have a Periodic Table? "I was going home to dinner, past a shallow pool, which was green with springing grass... when it occurred to me that I heard the dream of the toad. It rang through and filled all the air, though I had not heard it once. And I turned my companion's attention to it, but he did not appear to perceive it as a new sound in the air. Loud and prevailing as it is, most men do not notice it at all. It is to them, perchance, a sort of simmering or seething of all nature. That afternoon, the dream of the toads rang through the elms by Little River and affected the thoughts of men, though they were not conscious that they heard it. How watchful we must be to keep the crystal well that we are made clear!" Thoreau How reminiscent of Emerson's: "To speak truly, few adult persons can see nature. Most persons do not see the sun. At least they have a very superficial seeing. The sun illuminates only the eye of the man, but shines into the eye and the heart of the child. The lover of nature is he whose inward and outward senses are still truly adjusted to each other; who has retained the spirit of infancy even into the era of manhood. … In the woods, we return to reason and faith. There I feel that nothing can befall me in life, no disgrace, no calamity, (leaving me my eyes,) which nature cannot repair. Standing on the bare ground, my head bathed by the blithe air, and uplifted into infinite space, all mean egotism vanishes. I become a transparent eye-ball; I am nothing; I see all; the currents of the Universal Being circulate through me; I am part or particle of God. "

Periodic Table of the Elements Resource-World.Net Home Periodic Table Consumer Goods Natural Resources Resource Issues Search this site! powered by FreeFind An amazing number of elements touch our lives everyday, either in the consumer items we use, the foods we consume or the energy sources that drive our society. An element's uses depend upon the properties of the element and its various compounds. The periodic table is a useful means of classifying the elements into rows and columns determined by the elements' atomic numbers (number of protons in the nucleus). The rows and columns also group elements by similarities in chemical and physical properties. The periodic table following serves as an entrance into pages on the individual elements. The pages list various properties of the elements, historical information on discovery and naming of the elements, interesting facts, their uses and sources. The material is by no means exhaustive, and will be updated as needed. If you find errors, or have material to be added, please contact me at webmaster@mail.resource-world.net

56. Origin Of The Periodic Table The Origin of the periodic table. I know what the periodic table looks like, butwhere did it come from? Whose idea was it to arrange the elements this way? http://www.colorado.edu/physics/2000/periodic_table/

The Origin of the Periodic Table I know what the periodic table looks like, but where did it come from? Whose idea was it to arrange the elements this way? In 1869, a Russian chemist named Dmitri Mendeleev came up with a way of organizing the elements that were known at the time. He set them out in order of atomic weight , and then grouped them into rows and columns based on their chemical and physical properties. 1869...that's way before the , or even the Rutherford model That's right. Mendeleev had no idea what atoms were made of or why they behaved as they did. Nevertheless, he was able to put together the periodic table almost as we know it todayexcept that some elements were missing, because they were unknown in 1869. Based on the gaps in his table, Mendeleev even succeeded in predicting the existence and properties of several new elements. That's pretty impressive. Can you tell me more about how Mendeleev organized the table? What kinds of properties did he use? His basic rule was this: the elements in any column, or
