Element Properties
Maple also contains element properties and isotope properties.
Elements
Maple supports the first 112 elements of the periodic table, plus elements
number 114 and 116. Each element has a unique name, atomic number, and
chemical symbol. You can specify an element using any of these labels. For
a complete list of supported elements, refer to the ?ScientificConstants/ele-
ments help page.
Maple supports key element properties, including atomic weight (atomic-
weight), electron affinity (electronaffinity), and density. For a complete list
of element properties, refer to the ?ScientificConstants/properties help
page.
Isotopes
Isotopes, variant forms of an element that contain the same number of protons
but a different number of neutrons, exist for many elements.
To see the list of supported isotopes for an element, use the GetIsotopes
command.
>
Maple supports isotopes and has a distinct set of properties for isotopes, in-
cluding abundance, binding energy (bindingenergy), and mass excess
(massexcess). For a complete list of isotope properties, refer to the ?Scien-
tificConstants/properties help page.
Accessing an Element or Isotope Property Definition
The GetElement command in the ScientificConstants package returns the
complete definition of an element or isotope.
