Element
(number, name, symbol, mass)¶ An Element represents a chemical element.
The simtk.openmm.app.element module contains objects for all the standard chemical elements, such as element.hydrogen or element.carbon. You can also call the static method Element.getBySymbol() to look up the Element with a particular chemical symbol.
Element objects should be considered immutable

__init__
(number, name, symbol, mass)¶ Create a new element
Parameters: - number (int) – The atomic number of the element
- name (string) – The name of the element
- symbol (string) – The chemical symbol of the element
- mass (float) – The atomic mass of the element
