        This is version 4.1 of the Periodic Table of Elements, made by Kostas Tsigaridis. It is free to use, and if you decide that you like it or find it useful, you can drop me an e-mail, telling me your name. This will give me motives to carry on, and make more complex works in the future. Please feel free to contact, if you find out inaccurate or incomplete information. Please make sure that you 're going to fill in your comments in the GuestBook, after a careful view of the Periodic Table. You can also subscribe to the mailing list of the Periodic Table, and get informed on time for future releases and updated versions of the Periodic Table.

        It is strongly recommended that you use Microsoft Internet Explorer (version 4.0 or higher). Sorry, but if you use another Browser you might have problems viewing. The reason is that I use a lot of JavaScript stuff, in the same time with frames. Many Browsers are not compatible with these things, and others use a little different syntax. Netscape users (version 4.0 or higher) are able to see all pages, but not recommended.

        If you want to have an easy-to-remember address, you can use http://ptoe.move.to/ as a reference. It is a very flexible one, and even if the original page is being moved to another page, this link will never be broken! If you prefer to use the original address of the Periodic Table, you can bookmark it now: http://atlas.chemistry.uoc.gr/ptoe/.

        The Periodic Table has a lot of features, and as the time goes by, will become more. There is also a great information database, a very friendly userface, and a nice way to categorize things. This version, and the others following, will become your best friend!

The use of this version of The Periodic Table is simple. Here is what you can find out:

  • General information about an element. Here you can find general information about the elements, such as the name and name origin, a brief description, who discovered it, where and when, where you can find the element, where it is used, and its crystal structure. Here you can also find many images of the minerals that elements can be found, thanks to 'Amethyst Galleries, Inc.'.
  • Elements Data. In this section you can find a large amount of information about the element properties: Atomic number and weight, shells and filling orbital, melting and boiling point, covalent and atomic radius, atomic volume, electronegativity, oxidation states, 1st, 2nd and 3rd ionization potential, density, specific heat, heat of vaporization and fusion, electrical and thermal conductivity.
  • Element Nuclides. The place with the information for most of the element isotopes. You can find the abundance, mass, spin, half life and decay modes of most known isotopes.
  • Custom Charts. Here you can create charts of the element properties, check their periodicity, and even print them!
  • Calculate the molecular mass of a compound.
  • Select the info you want to see, and make your custom printable copy. Just select in the left, and click create. So easy! Please remember to print in landscape mode.
