Free periodic table software for mac

Our Periodic Table application was designed with ease of use in mind, and elements can be viewed in many different ways:
- Traditional table, colour coded with atomic numbers
- List view, both names and symbols in alphabetical order
- Sort view allows the elements to be sorted based on their numerical data, from boiling point to atomic radius
Elements can be selected from anywhere in the application, showing a detailed view of its attributes.
The Periodic Table is completely free of charge, although a huge amount of time was put into making it, so donations are greatly appreciated.
System requirements:
- iPhone

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.

RefEls is a Perl script that lets you look up and increase knowledge of the periodic table of elements. For all of the elements on the table the name, symbol, atomic number, and atomic weight have been referenced (the atomic weights for some elements are only those of the most common or well known types of the element, and may not be the only possible atomic weight).

There are two functions in the program. One is used to look up information about elements, and the other is a function like flash cards that allows you to test and improve your knowledge of the elements.

The reference section is used by typing in an attribute of an element, and then getting all of the information referenced about that element. You can type in the name, symbol, atomic number, or atomic weight to get the information about an element.

The flash card section works like normal cardboard flash cards: you are given one quality of an element and you have to give another quality of the same element back. One example would be the computer giving you the name of element and you having to give the atomic number for that element.

iMass (short for isotopeMass) includes a molecular mass calculator, a periodic table of the elements, an isotope distribution graph and a calculator that computes elemental compositions matching a given mass.
iMass understands complex chemical formulas as well as user defined abbreviations for commonly used formulas.
Enhancements:
- New features include overlaying of isotope distribution graphs and exporting of graph data as tab delimited text.

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.
