  From David Hsu at MIT, this shows the Periodic Table of the Elements, with a legend defining what type of element each one is. Each element leads to an in depth discussion of it's properties.

  Overview of Website:  This website is designed to explore the elements and the periodic table in an interactive way.  It goes through both the history and the attributes of each of the elements.  It does this through a narrative and various youtube videos about the elements.
  
  Content:  The content of this site can be used two ways.  The first is the instructor can go through before class and pick out interesting information and videos that are given and bring it to the lesson that is planned.  The second method would be allow students to click through the elements and find interesting facts.  This way, they are leading their own learning.  The only thing I would be worried about is that the information is a little much for younger grades.  I would guide them during class. I would use the content to help demonstrate the periodic table and elements.
  
  Design: The design of this is decent.  A pre and post adolescent can easily navigate it by clicking on the elements her or she would want to work on.  It would be best used for high school students, however, middle school could learn from it as well.  It allows for exploring the periodic table in a more interesting manner than in class options would.

  • The periodic table we use today is based on the one devised and published by Dmitri Mendeleev in 1869.

     

    Mendeleev found he could arrange the 65 elements then known in a grid or table so that each element had:

     

    1. A higher atomic weight than the one on its left. For example, magnesium (atomic weight 24.3) is placed to the right of sodium (atomic weight 23.0):

    The Periodic Table

     

     

      

     "If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. This is expressed by the law of periodicity."  
     Dmitri Mendeleev, Principles of Chemistry, Vol. 2, 1902, P. F. Collier, p17. 
    
     

      

     "We have here a proof that there is in the atom a fundamental quantity, which increases by regular steps as one passes from one element to the next.  This quantity can only be the charge on the central positive nucleus, of the existence of which we already have definite proof." 
     Henry Moseley, Philosophical Magazine, Vol. 26, 1913, p1030. 
    
     

      

     "The chemistry of an atom depends only on the number of electrons, which equals the number of protons and is called the atomic number. Chemistry is simply numbers, an idea Pythagoras would have liked. If you are an atom with one proton, you are hydrogen; two, helium;....."

  Chemicool was created by David D. Hsu. of the Massachusetts Institute of Technology in 1996. Chemicool went online in 1996 and since then has been trying to help out anyone involved in chemistry.
