Calling Sequence

Parameters

Description

Examples

Calling Sequence

GetElement( descriptor, 'symbol', 'name', 'names', prop_name )

Parameters

descriptor

-

name, symbol, or atomic number of an element, or isotope syntax of an isotope. For a description of the isotope syntax, see Element

'symbol'

-

(optional); include symbol in output

'name'

-

(optional); include name in output

'names'

-

(optional); include names in output

prop_name

-

(optional) symbol; include value of specified property(ies) prop_name of element (or isotope) in output symbols. This parameter can be repeated to specify multiple properties.

Description

• 

The GetElement( descriptor ) command returns the definition of an element or isotope in the ScientificConstants package.

  

For an element, the expression sequence returned consists of the element's atomic number and equations that specify its symbol, name, set of multiple names, and defined properties, in the same format used for AddElement.

  

For an isotope, the expression sequence returned consists of the isotope syntax in atomic_symbol[mass_number] format and equations that specify its defined isotopic properties, in the same format used for AddElement.

• 

If none of the optional parameters are given, the full definition of the element or isotope is returned.  If any of the optional parameters are given, the output is restricted to the indicated items.

  

Only the optional property name parameters are valid for isotopes. That is, you cannot specify 'symbol', 'name', or 'names'.
