Fixed issue in which electron configuration display from the Element Browser did not work.

Minor user interface updates

The Atomic Dashboard is now a Universal app (runs natively on all Mac processor types). New molecular search code to adapt to changes in the PubChem molecule search mechanism (API). Bug fixes.

Version 2.2 runs on macOS 11 Big Sur! Fixed button positions in Model Window Options.

Updated to run on macOS 11 Big Sur.

Language translation strings updated.

Added display of all known ionization energies in the Element Browser (opened by clicking on element symbols). Performance enhancements.

Fixed a bug in the 3D Molecule Library.

Converted to a 64-bit app that will run on the latest versions of MacOS. Updated elements data. Build your own atoms using the new Electron Configuration Lab!

New Properties • Elemental abundance in the solar system • Listing of the elements' most common isotopes New 3D Molecule library • Search for interesting molecules from a collection of 25 million 3D models available from the PubChem database at the U.S. National Institutes of Health. Search the PubChem database by by molecule name, by chemical formula, or by just searching for terms as wide ranging as "vitamins," "hydrocarbons," or "detergents." Download these molecules and inspect them using the unique 3D viewing tools in The Atomic Dashboard's Model Window. • Explore the bonding characteristics of molecules, including their covalent bonding structure ("3D Lewis Structure") and the locations of lone pair electrons. If you're taking organic chemistry, zoom in and examine the 3D features of organic molecules that are so important to reaction mechanisms. New Molecular Mass Calculator • Calculate the molecular mass and percent composition of elements that make up a molecule by entering its chemical formula, e.g., CH3CO. New 3D Viewing Options for Atoms, Molecules and Orbitals • Atomic Labels -- Displays characters on each atom that represent its atomic symbol or its atomic number. • Bond Pairs Model Type -- Represents bonds as pairs of small spheres representing the shared electron pairs in covalent bonds. This representation, along with the display of lone pairs can be thought of as a "3D Lewis Structure." • Lone Pairs -- Displays a pair of small spheres for each set of lone pair electrons, and/or a thin mesh representing the "lobes" of electron density where the lone pairs are located. • Orbital Color Selection -- The "clouds" of dots that represent the orbitals can now be colored in one of two ways. The first option is to color each orbital by its type, e.g. 1s, 2s, 2p, etc. The second option is to color code each orbital dot by the sign of the orbital wavefunction at that point -- with red dots representing positive values and blue dots representing negative values. • Background Color -- Sets the Model Window's background color -- some models display better on a lighter background. For example, the display of orbitals when using an LCD projector typically exhibits the most contrast on a white background. New Detailed Help System • The Help System now provides more detail, direct access to Help resources from all program windows, and easy navigation between topics.
