Periodic Table is an easy-to-use periodic table for Macintosh. Features include:Quick access to a wide variety of atomic properties (we recommend keeping an alias to the program in your Apple menu!)

Relative values of many atomic properties on the periodic table are viewable as color scales.

Quick molecular weight calculations.User-friendly interface.User configurable--choose a table to view at startup, choose units of displayed values.Controls and design help to emphasize relationships between elements.

Here are some key features of "Periodic Table":

· Quick access to a wide variety of atomic properties
· Relative values of many atomic properties are viewable as color scales and line graphs.
· Quick molecular mass calculations.
· Clean, clear, easy to understand interface.
· User configurable--choose a table to view at startup, choose units of displayed values.
· Controls and design help to emphasize relationships and trends between elements, and the structure of the table itself.
· available for Mac OS X, Mac OS 9, and Windows XP!

Limitations:

· 30-day trial
Several features are disabled:
· The molecular mass calculator (understands parentheses and hydrated compounds).
· Data and unit-switching is only available for "red" (physical) properties.
· Saving certain preferences (lets you set a startup periodic table, etc.)
· Most of the properties periodic tables and property graphs are unavailable until you register except for the physical (red) properties, discovery nation.
· The Abundances, Discovery, and Uses buttons and information on the element information screen.
· You cannot save/export as images any of the property periodic tables, or save custom tables.
· Graphing only allows the built-in sample graphs and physical properties until you register.
