The elements class gives a simple interface to basic data about chemical elements. The data is automatically generated from the Blue Obelisk data repository.
The atomic numbers between the symbolic constants CustomElementMin and CustomElementMax are used to represent non-elemental entities, such as particles or structures units from MD simulations. Custom elements names and symbols are returned as name="CustomElement_aa" and symbol="Xaa", where 'aa' is some combination of lowercase letters that is unique to the particular custom element atomic number. For all custom elements, the radii will match Carbon, the color is random (but consistent), and the mass is zero.

static |
Get the number of elements in the database.
|
static |
Get the atomic number from the supplied element name. If the name is not recognised then Avogadro::InvalidElement will be returned. 0 represents the dummy atom ("Dummy").
|
static |
Get the atomic number from the supplied symbol. If the symbol is not recognised then Avogadro::InvalidElement will be returned. 0 represents the dummy atom ("Xx").
|
static |
Given a string, attempt to identify an element symbol, name, or atomic number. This method is slower and less reliable than the atomicNumberFrom*() methods, and is only intended for making an initial guess of user input.
|
static |
Get the name of the element with the supplied atomic number.
|
static |
Get the symbol of the element with the supplied atomic number.
|
static |
Get the mass of the element with the supplied atomic number.
|
static |
Get the Van der Waals radius of the element with the supplied atomic number.
|
static |
Get the covalent radius of the element with the supplied atomic number.
|
static |
Get the default color of the element with the supplied atomic number. This is a pointer to a static three component unsigned char color.
