Get Elements - Maple Help

ScientificConstants

 GetElements
 list the descriptors of selected elements

 Calling Sequence GetElements( prop_name, output_opt )

Parameters

 prop_name - (optional); restrict to elements with property(ies) prop_name defined. This option can be repeated to specify multiple properties. 'output_opt' - (optional); equation of the form output=form, where form is one of 'symbols' (default), 'atomicnumbers', or 'names'; specify form of element descriptors to be returned

Description

 • The GetElements() command returns an expression sequence containing selected elements of the periodic table in the ScientificConstants package.
 • If any prop_name option(s) are given, only elements with these properties defined are returned.  The prop_name option(s) must be non-isotopic properties.
 • If the 'output=symbols' option is given, the symbols of the elements are returned.  This is the default.
 • If the 'output=atomicnumbers' option is given, the atomic numbers of the elements are returned.
 • If the 'output=names' option is given, the names of the elements are returned.
 • The sequence of symbols, atomic numbers, or names is ordered by atomic number.
