===================
  ChemTable v2.16
===================

ChemTable is a freeware Periodic Table application that runs on monochrome
Palm OS handhelds.  The information contained in this program was collected
from a variety of websites, handbooks, textbooks, and commercial periodic
charts (see Sources.txt).

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 chemical/
physical properties.  In the Options menu, you can choose to 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 between
the two sections, tap on the left or right arrow buttons.

While I have tried my best to ensure the accuracy of the data presented in
ChemTable, I cannot guarantee that everything is correct.  For "mission
critical" applications, please check the data against values from other
sources.

Change History:

v2.16
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.

Lookup of elements in the alphabetically sorted name list is now easier.
Enter a letter in the Graffiti area and element names that begin with that
character will scroll into view.  This is not a full-blown search capability
- you cannot enter multiple characters to find a specific element.  Also
note that names beginning with a letter from V to Z can never appear at
the top of the list window - the list cannot be scrolled any further.

Atomic radii are now given in picometers instead of Angstroms.

Fixed a number of minor bugs and cosmetic flaws.


v2.15
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
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
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
Added 2nd and 3rd ionization energies.  Revised the oxidation states for
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.)

v2.09
Revised the crystal structure data (now have hexagonal close-packed vs
hexagonal).  The form that displays the properties for a selected
element now includes the element's classification.  Added the series
"Transactinides".  Fixed a minor cosmetic problem that occurs when ChemTable
is run under Palm OS 5.0.

v2.08
Changed some of the forms from modal to modeless.

v2.071
Corrected a couple of errors.

v2.07
Updated average atomic mass data using IUPAC 1999 values.  A number in
parentheses at the end of an atomic mass value indicates the uncertainty
in the last digit.
Also revised melting point and atomic radii data.

v2.06
Minor update of data.

v2.05
Removed element 118 ("Ununoctium") from the table -- the claim for
its discovery has been retracted.
Made some changes to the thermal conductivity data.
Pressing the hardware up/down buttons allows you to jump between the two
halves of the periodic table.

v2.04
Updated enthalpy of fusion, enthalpy of vaporization, specific heat capacity,
thermal conductivity, and electron affinity data.

v2.03
Revised the density values for many elements.

v2.021
Fixed the creator ID.

v2.02
Added electron affinity data.

v2.01
Updated the values of various chemical/physical properties.

v2.0
Conversion of original Java program to C.
