(08/05/10) – Added Element 117 (Ununseptium).
Renamed Ununbium (Element 112) to Copernicium. Updated the ionization energy data.
(05/05/09) – Minor bug fixes.
(18/01/09) – Updated
the melting point, boiling point, enthalpy of fusion, and electron affinity data. Also made a number of code optimizations.
(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.
(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.
(20/01/08) – Updated
the atomic weights to IUPAC 2007 values. Numerous bug fixes
and code optimizations. Improved support for localization and
(18/01/07) – Updated
the mass numbers of radioactive elements to the latest IUPAC
values. Added support for 240x240 resolution. Now runs on
(01/08/06) – Updated
the atomic weights to IUPAC 2005 values. The element list can
now be sorted by name, symbol, or atomic number.
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
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.
a bug that caused the program to crash on the Tungsten™ T3.
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.
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.
the electron configurations to show orbitals in order of
increasing energy. In general, the orbitals are filled in the
2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p
(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.
(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
(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
(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.
(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.
(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.)
