ChemTable - A Periodic Table For Palm OS

ChemTable is a freeware periodic table application that runs on Palm OS® handhelds. The program is quite straightforward to use. Tapping on any of the element boxes in the periodic table will bring up a form showing a list of physical/chemical properties. You can display either element symbols or atomic numbers in the table. You can also select a subset of the elements for display (Transition Metals, Halogens, Noble Gases, etc). Only half of the periodic table can be viewed at a time. To switch sections, tap on the left or right arrow button.

The color coding for the various element categories can be changed via a Color Settings form. Simply tap on any of the colored boxes in that form to display a Pick Color dialog.

ChemTable also features an element list that can be sorted by name, symbol, or atomic number. To view element names or symbols that begin with a particular letter, enter that letter in the Graffiti input area. The list will automatically scroll to the required position.

Using a resource editor, you can edit the data in ChemTable.

ChemTable requires Palm OS 3.5 or later.

Version History

v2.32 (08/05/10) – Added Element 117 (Ununseptium). Renamed Ununbium (Element 112) to Copernicium. Updated the ionization energy data.

v2.31 (05/05/09) – Minor bug fixes.

v2.30 (18/01/09) – Updated the melting point, boiling point, enthalpy of fusion, and electron affinity data. Also made a number of code optimizations.

v2.29 (05/10/08) – Using the 5-way navigator to move between the two halves of the periodic table is now much easier. For example, if "Co" is highlighted by the blue focus ring, pressing the right rocker key moves the highlight to "Ni" in the other half of the table. Also made a number of minor bug fixes.

v2.28 (30/08/08) – Added support for 5-way navigation (Palm® TX, Treo™ 600 or higher, and Centro™). Fixed a rendering problem on devices that display more than 256 colors.

v2.27 (20/01/08) – Updated the atomic weights to IUPAC 2007 values. Numerous bug fixes and code optimizations. Improved support for localization and user customization.

v2.26 (18/01/07) – Updated the mass numbers of radioactive elements to the latest IUPAC values. Added support for 240x240 resolution. Now runs on StyleTap®.

v2.25 (01/08/06) – Updated the atomic weights to IUPAC 2005 values. The element list can now be sorted by name, symbol, or atomic number.

v2.23 (25/07/05) – Added isotope abundances (IUPAC 1997). Revised the electron affinity data (Values are from the CRC Handbook of Chemistry and Physics, 80th Edition). Improved support for grayscale devices.

v2.22 (30/07/04) – Added a mode selection popup to the top right corner of the periodic table and element list forms. Renamed Unununium (Element 111) to Roentgenium. Minor bug fixes.

v2.21 (17/06/04) – Fixed a bug that caused the program to crash on the Tungsten™ T3.

v2.20 (12/06/04) – Major overhaul of the internals. Added support for color. The minimum requirement is now Palm OS 3.5. If a previous version of ChemTable is installed on your handheld, you should delete it before installing the new version.

v2.19 (30/07/04) – This is the last version of ChemTable that runs on Palm OS 3.1. Except for color, this version has the same features as v2.22.

v2.18 (20/03/04) – Modified the electron configurations to show orbitals in order of increasing energy. In general, the orbitals are filled in the following order:

1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p

v2.17 (07/02/04) Added Ununtrium and Ununpentium (Elements 113 and 115). Fixed minor bugs. Now runs more reliably under low memory conditions. Changed the way the application preferences are loaded/saved. If you are installing over a previous version of ChemTable, you may need to set your ChemTable display options again.

v2.16 (07/12/03) Updated the enthalpy data for atomization, vaporization and fusion. The new values for vaporization and fusion are from Lange's Handbook of Chemistry (15th Edition, 1999) and the CRC Handbook of Chemistry and Physics (83rd Edition, 2002-2003). The enthalpies of atomization are from Macmillan's Chemical and Physical Data (1992). All enthalpies are per mole of atoms. Revised some of the crystal structure and thermal conductivity data. Atomic radii are now given in picometers instead of Angstroms. Fixed a number of minor bugs and cosmetic flaws.

v2.15 (22/06/03) Modified the user interface in the Display Options form. Added a vertical scrollbar to the sorted name list. In the element details form, wrapped text is now indented. Moved "Electron Configuration" close to the top of the element details list.

v2.12 (05/06/03) Added an option to display element names in an alphabetically sorted list. Display preferences are now saved between sessions. Renamed Ununnilium (Element 110) to Darmstadtium.

v2.11 (10/11/02) The Lanthanides are now defined as the 14 elements that follow Lanthanum (Ce to Lu). Similarly, the Actinides are defined as the 14 elements that follow Actinium (Th to Lr). Also made a number of cosmetic changes.

v2.10 (30/07/02) Added 2nd and 3rd ionization energies. Revised the oxidation states for some of the Noble gases. Groups are now labelled according to the IUPAC convention. (CAS group labels are still provided in the forms that display element properties.)
