Free periodic table of the elements software software for mac

XMLSpear a powerful graphical tree editor, targeted to check, and correct XML files in a simple way.
You can assign a schema or DTD to validate the xml. For correcting not-wellformed xml a simple source editor is available.
Main features:
- Full schema validation using DOM3 in Xerces 2.8.0
- Tree editor for inserting and deleting nodes
- real-time validation while editing table and element view
- GUI components reflecting the xml schema
- Visual and textual feedback for errors
- Support for multi-document view
- Generation of complete xml documents from schema
- Opening and correction of not-well formed XML
- Plug-In interface for extending functionality
- Flexible encoding (character set) support
- Project viewer
- Integrated text and HTML plugin.
Enhancements:
Solved bugs:
- Incorrect display and behavior of default button in dialogs
- Double-clicking folders in the file tree to expand the tree, incidentally triggered an action to open a file.
- After deleting all file trees, a newly add tree only showed up after opening a source or restarting XMLSpear
- The filetree tab, which displays the top directory name, was not updated after a folder was selected as the new root.
- Small problems with the item names in the filetree popup menu in java 1.6
- Incorrect positions in the find-replace (especially concerning Windows users after a saving a document.
- Redundant extra line number in text editor
- Several XML formatting issues in the source view.
- Loss of linefeeds after editing text in tree tabel
- Incorrect behavior regarding to mixed elements with multiple text nodes
- Prefix initially not filled in dialog for inserting elements or attributes
New functionality:
- Move up possibility in file tree
- If you select a .xsd file in the tree, there will be a new option in the popupmenu to generate a XML instance from the selected schema
- A totally new find-replace dialog with the possibility to mark text.
- A find function for the tree table
- Improved support for mixed elements. You can switch to an advanced mode, where the textnodes will displayed in the tree.
- If a text has linefeeds or tabs you are not allowed editing the text in the table cell. This will be indicated by a special button which brings up a text editor.
- In edit mode, you will have a button in each cell to switch to a full functional tekst editor.
- If a value is part of an enumeration, it will be showed in the table. In previous versions the combobox was only showed in editMode.
- Xpath display of each selected element in the tree table view
- Insert and editing of CDATA and text nodes in the tree table view
- Improved schema support for enumerations and fixed values
- Unformat option in the XML source view
Updates:
- Alphabetical listing of elements in dialogs
- Collapse and Expand actions are now local to the selected node, instead of to the complete tree
- The warning message for large XML files is removed. If a XML file is displayed in the treetable, it will no longer be fully expanded. This will save a lot of load time. It is not a good idea to fully expand such a tree from the rootlevel. This will be slow or may cause an out-of-memory exception.

The Periodic Table is a very interesting widget that allows you to click on an element to display basic information and properties, such as atomic mass, density, melting point and more.
Double-clicking on an element will open a link to its Wikipedia page to provide additional information.
Enhancements:
- Increased the font size of the common oxidation states for clarity
- Fixed a typo on the default startup image
- Centered the done button on the back

Simple Periodic Table Utility that can be used for general information, projects, flash cards, history and uses of elements, and Molecular Mass Calculator.
Enhancements:
- Recoded in Cocoa for functionality, and Mac OS X compliance.
- History and Uses of each element.
- Molecular Mass Calculator.

Elemental is a multifaceted periodic table of the elements with search capabilities. It is currently still largely under development, but I have deemed it stable enough for a an alpha release.

It features colourful tables and legends, an information window with masses, and tables not only of the traditional type, but of crystal structures, electron blocks, radioactivity, and states of matter.

Elemental is a Universal Binary and requires Mac OS X 10.4 or later.

Element Style is a MultiAd Creator AppleScript that selects all elements on the same spread that have an element style matching the currently selected element.

Completly freeware.

ChemBuddy is a chemical analysis program for students, chemists, and hobbyists alike. It was created to perform many functions from various aspects of chemistry.
Cocoa/Objective-C chemical analysis and computation program; includes gas laws, solutions/solubility, stoichiometry, periodic tables, etc
Enhancements:
- I created a new, native project file for ChemBuddy, under the Xcode developer tools on Mac OS 10.3 (Panther). This, ironically enough, seems to have allowed me to make it compatible with Jaguar, as I am now easily able to manipulate the target OS version.
- The programme should function under Jaguar now.
- The main interface has been cleaned up quite a bit, and now takes the form of an outline view, rather than tab views with buttons. Its behaviour could still use some further refinement. This has, however, required me to change the Controllers.plist file from earlier versions: it is now somewhat more complicated, and has been renamed ControllerHierarchy.plist; and I have added yet another file, Controllers.plist, which is simply a list of the controllers. This, needless to say, is quite redundant, but Im still trying to work out the best solution (perhaps someone else may examine the source and shout, Why Reka! I have found it!).
- The version issue has been fixed. Several individuals noted that the previous distribution was supposed to be 1.1a2, rather than 1.1a1, but (due, again, to compiling in an older project format) this version-change appeared only on 10.3, rather than 10.2, which still showed my earlier, private alpha version. Future versions should hopefully experience no such inconsistencies.
- The periodic tables have been implemented more fully. Atomic numbers, smaller than the symbols and dark grey in colour, now appear atop the symbols.
- The nib files from the previous alpha maintained atomic symbol and number in the nib file itself as title and alternate title, respectively, for purposes of consulting PTCells.plist, a property list dictionary, for data. I migrated the property list to an array, accessed via the tags of cells (transparent ones all have a tag of -1 now).
- I also use attributed strings for the numbers and symbols on the periodic table buttons at this point. Older methods called from drawInteriorWithFrame: have been removed, as have several commented-out ones.
- The legends, as a final note, still leave something to be desired, as they are clunky and somewhat difficult to maintain at this point.
- I removed the outdated online help from the project, thus trimming four-fifths of a megabyte from the programme size.
- I deleted an extraneous nib backup from the English.lproj folder.
- The Italian.lproj folder is not included with this release, as it contained only a localised credits file; it and other localisations will be reimplemented at some point, hopefully by user and developer contributions.
