This equation will return the selected details data of the requested Element.

 Units for Atomic weight are expressed in grams per mole.  Isotopes and molecular compositions are not represented in this equation.

Notes

This equation is linked to a Dataset with information about the Elements in the Periodic Table.

The data fields in this dataset include:

• Name Atomic Number
• Symbol
• Atomic Weight
• Melting Point
• Boiling Point
• Density
• Year Discovered
• Ionization Energy (eV)
• radius - empirical
• radius - calculated
• radius - van der Waals
• Group (representing column in Periodic Table

This equation will let you select an Element (by Atomic Number) and also select which data element to Display for that Element.
