Periodic Table of the Elements

The Tools/Elements menu item brings up the Periodic Table of the Elements.

Clicking on an element brings up more detailed information.

The full name of the element and its family are shown along with its valency. Symbols show the element's state at room temperature, and whether it is radioactive or toxic. The atomic number, weight, and physical properties are also shown with adjacent buttons. If the button is pressed, you are returned to the calculator with that value entered into the display. The units used to display properties can be changed by selecting the units in the Units dialog and selecting it as the "To" units.
