My goal is to use the periodic table of elements (or a list) to get information about a specific element in Java. I want to search it by atomic number and symbol (but that conversion should be simple).
There's a bit of java kung fu going on here that deserves an explanation. The map is put inside a static inner (holder) class so it gets initialized before the enum instances are initialized, that way they can add themselves to it. If not in the inner static class, it would not be initialize, because the first thing initialized in the enum class must be the instances, but static inner classes are initialized before the class is initialized.
The PTEO provides the mean concentration, ocean residence time, and, where available, a profile for each element in the Atlantic and Pacific oceans. The mean concentrations of each element come primarily from Nozaki, with a few exceptions noted within the PTEO. Each concentration has been converted to molal (mol/kg) or molar (mol/L) units. These values are essentially interchangeable, differing only by the density of seawater, which is about 1.02 kg/L. Chemical speciation comes primarily from the review of trace metals in seawater by Bruland (1983) and the review of metal speciation by Byrne et al. (1988). There are no recent compilations of residence times for elements in seawater, so the source for each residence time is explained on the page for each element. A summary table of the mean element concentrations and residence times is also available. The profiles do not always provide a sense of the variability of elements in the ocean and the impact that this variability can have on biogeochemical processes. Where possible, sections of chemical distributions through the ocean or records of temporal variability have been added to the pages. Many of these extra plots were prepared with the program Ocean Data View, written by Reiner Schlitzer. Ocean Data View has proven to be an extremely helpful tool for visualizing this chemical variability.
good evening everyone
im in a mood that would let me make a Periodic Table for kids ,so each button is going to have the name of the elements and when you click on one of them you would have a form that contain the detelis of this element , now let get to the hard part
I want to know how can I make the navigation on periodic table elements by rows (Horizontal) or by columns (vertical) or by blocks based on my choice from a drop down list how can I code that in C#?
at first i though it is a good idea and easy to implement but when i started to implement it in the c# i really couldn't make it probably it's beacasue that i dont know so much about c# like java and javascript !
But something was still missing. After years of refining my analytical interests, I still yearned for that element of science that I had grown to love as a first grader. I was still missing that feeling of success after persevering through a difficult word problem or struggling through memorizing the first 100 digits of pi. It was then that I discovered biology. As I explored various research studies that not only furthered scientific understanding but also helped millions around the world, I knew that this was what I wanted to do. Medical research, specifically in cellular biology and genetics, condenses my passion for mathematics, biology, and discovery into one distinct goal. Whether it be analyzing patterns in the genome, generating computer models of clathrin-mediated endocytosis, or studying the chemical composition of organic molecules, cellular biology embodies my passions just as well as the periodic table.
For example, the periodic table of elements uses both rows and columns to help scientists visualize the similarities between elements that sit on the same row, and the commonalities between elements that reside in the same column.
One can query rows and columns in a database, and deduce information from how elements are organized in columns and rows in a periodic table. At the same time, one can also admire a row of ducks as they swim by, and be humbled by the beautify of the Corinthian or Doric columns that hold up an ancient Greek building.

Acrobat Periodic Table
This is a simple, single sheet periodic table which contains the symbol, name and atomic mass of each element. It is provided in Adobe Acrobat PDF format, and is available for downloading, viewing, and/or printing. It requires version 3.0 or greater of the free Adobe Acrobat Reader.
The Atomic Mac and The Atomic PC
The Atomic Mac is an award winning periodic table of the elements program for the Mac (or the PC). They make a very strong claim: "No other periodic table of the elements has more data than The Atomic Mac/PC." The list of information displayed for each element is impressive. A molecular weight calculator is included in the software package. An evaluation copy is available for downloading and will allow you to view data from some of the elements. The registration cost is $25.
BCIT Chemistry Resource Center
The BCIT Chemistry Resource Center is a wonderful online resource for chemistry which includes descriptions (and pictures) of more than 100 elements of the periodic table. There is also a periodic table quiz and a crossword puzzle based upon the elements.
Element Games
This page provides links to many games designed around the periodic table of the elements. Some of the games are internet-based while others are paper-based (with downloadable files). The internet-based games require a JavaScript-enabled web browser. These games are hosted by the Thomas Jefferson National Accelerator Facility (Jefferson Lab). NOTE: Some of the internet-based games can be customized, and others will give the student an option allowing them to find out why their incorrect answers were wrong!
Elemental Spectra
This JAVA applet (a part of the Virtual Laboratory at the University of Oregon) displays the periodic table of the elements. Clicking on an element will display its line spectrum (emission or absorption).
HRW Periodic Table
A link to a colorful, printable copy of the periodic table provided by Holt, Rinehart and Winston. Requires the free Adobe Acrobat Reader to view and print. Note: This periodic table is as up to date as can be! HRW has removed elements 116 and 118 but included a note about their discovery and subsequent retraction by the discovering scientists. While they haven't placed 116 back on the table since its discovery by Russian scientists, it is up to date with all official elements, including element 110 (Ds).

The Path to the Periodic Table
These pages are part of the Chemical Heritage Foundation web site. The CHF has published a book titled Chemical Achievers from which this information has been taken. The book "was designed to help teachers supplement science curricula with human stories of discovery in the chemical sciences." This link takes you to section four of the online version of the book where you will find out about nine people who were responsible for helping develop the periodic table.
Periodic Law
This page gives a nice overview of the development of the periodic table, a tour of its geography, as well as an overview of the trends found on the table. Concise and good for review.
Periodic Table
Periodic Table is a small periodic table of the elements program that displays the periodic table and gives basic information about each group and element. Versions are available for Macintosh and PowerMacintosh or Windows 3.x and 95. It requires 256 color display (it will not run with any other resolution). Periodic Table is FREEWARE!
