iChem 1.3

iChem, written in Cocoa for Mac OS X exclusively, is a full-featured periodic table and molecular weight calculator.
It offers a multitude of features you wont find in many other places. The molecular weight calculator alone is invaluable to chemistry professors, students, and practitioners the world across.
Main features:
- All the elements. Well, 110 of them anyway. How many do you need?
- Information on each element including melting point, energy of fusion, atomic radius, ionic charge, atomic mass, vaporization energy, and more! See the screens page for more.
- Drag and drop of element information into anything that accepts text!
- Gorgeous color-coded buttons for the element classes (Nonmetals, Transition Metals, Noble Gases, etc.) that you can turn on or off individually or as a group.
- An advanced molecular weight calculator that also calculates the % mass and % exact mass. Easily handles nested (i.e. C(CH3)4) formulas. In fact, even formulas as complex as "((C6H5)H2N)2(C7H5)2NH2 + (H2SO3)2" work!
- Handy features such as "Quick Open," a Dock Menu, and preferences.
Enhancements:
- Moved registration scheme to the FSS style
- Updated some information on a few elements
- Fixed a small leak in the molecular weight calculator.
