Element 1.5.2 for PalmOS(TM) Copyright (c) 1997-1999 Tom Bridgwater. [This file last updated 18 Apr 1999] --- Please read this before you go any further ========================================== Element 1.5.2 is shareware. To find out how you can (and why you should) register, read the enclosed file REGISTER.TXT. Before registering, please visit the following web page for the latest information: http://www.mindgear.com/ Installation ------------ Follow the instructions for installing applications included with your device and/or desktop software. Registration ------------ Once you have registered your copy of this program, you will receive your registration code via e-mail within a few days. You need to enter this code on the splash screen displayed when starting Element 1.5.2. Once the correct code is entered, Element 1.5.2 will immediately operate with all features of the registered version and no more registration reminders will be displayed. For information about how to acquire a registration code, please see the file REGISTER.TXT that is distributed along with this program. Main Display ------------ The main display consists of a graphic representation of the periodic table of the elements. Tap on a box in the table to select an element and display its properties. Above the table display are four fields, including: - Atomic Number (top-left) - Mass Number (top-right) - Symbol (center) - Element Name (bottom) Tapping on any of these fields will display a sorted popup list from which you can select elements by that property. Below the table is a scrollable list of 21 additional properties of the selected element. Information explaining each of these additional properties is available by selecting "Property Information" from the "Options" menu. At the lower-left corner of the table are three selectors (+, -, &) which are used in conjunction with marking (see below). Above the lanthanides on the right side are left/right arrows which are used to step through the elements. When stepping, the selection moves to the next element in the same marked-state as the current selection. Marking ------- You can mark elements based on any of the properties in the list at the bottom of the display. Elements are marked by comparing (equal, greater, less) a single property to the currently selected element (greater and less also imply equal). The result of the comparison is used to either add-to, remove-from, or limit (logical AND) the currently marked set. 1. Tap the desired property data to be compared. 2. Select the desired marking operation (add[+], remove[-], limit[&]). 3. Choose the desired comparison from the "Mark" menu. In addition to marking by comparison, you can change the marked-state of the selected element, mark all elements, or clear all marks by choosing the "Selected", "All", or "None" menu items, respectively. If the marking results in all elements being marked, the operation will automatically change to remove[-]. Likewise, if the marking results in no elements being marked the operation will change to add[+]. A single mark command can be retracted with the "Undo" item on the "Edit" menu. Selecting "Undo" a second time will undo the undo (i.e. redo the marking). Undo also resets the selected operation. Property Order -------------- For purposes of comparison the property data are ordered numerically except for the following, which are ordered as shown: Elec Cfg: As atomic number Family: alkali metal alkali earth metal transition metal chalcogen halogen noble gas lanthanide actinide Crystal: monoclinic rhombohedral orthorhombic tetragonal hex cubic bcc (body-centered cubic) fcc (face-centered cubic) State: solid liquid gas synthetic OxStates: Numeric by first listed state Oxide: amphoteric strong base mild base weak base neutral weak acid mild acid strong acid Any unknown datum (indicated with "-?-") is un-ordered and only compares as equal with other unknown data. Accuracy of the data -------------------- The data provided is accurate to the best of our knowledge. However, an amount of that data has been gathered by methods which cannot ensure 100% accuracy. We welcome all corrections, provided that they are accompanied by an appropriate reference to their source. Please send feedback to: element.feedback@mindgear.com The values of certain properties of some elements were unknown to us and have been substituted with "-?-" as a placeholder. We would especially like to receive feedback with values for such items. Version History --------------- 1.5.2 Corrected properties based on data in "The Elements", 3rd edition, by John Emsley. (Thanks to Mark A. Ordal of The Minnesota Academy of Mathematics & Science) Increased speed of sorting the popup lists. Added HotSync username display to the registration screen. Modified memory allocation for compatibility with future PalmOS devices. 1.5.1 Made resource loading more efficient to help alleviate a launching problem on some PalmPilot Personal devices. 1.5 Moved the details to the main display instead of a separate dialog. Added marking based on details data. Replaced Registration menu with a splash screen. Added clipboard paste to registration entry. Project converted to CodeWarrior R5. 1.0.3 No changes to Element. Project converted to CodeWarrior R4. 1.0.2 Made memory usage more efficient to help alleviate the 'Details' problem. Fixed a problem with the registration that would keep the response dialog from appearing when particular incorrect codes were entered. 1.0.1 Improved exception handling in order to identify a memory allocation problem which occurs on some devices when tapping the 'Details' button. 1.0 Initial release How to contact the author ------------------------- Any suggestions or bug reports are welcome.
