Atom object handles all quantities related to atomic species and their settings.

Creating atoms

Atomic objects are created either via dictionary lookups or via object creation.

C = sisl.Atom(6)
C = sisl.Atom[6]

are both equivalent.

The Atom class can be created to arbitrary precision

C = sisl.Atom(6,orbs=2,R=(2.,5.),mass=14,tag='C_hello')

which creates a Carbon atom with 2 orbitals, with 2 Å and 5 Å respectively. The atom has a tag which identifies it via the string 'C_hello' which makes it comparable to other Carbon atoms with different settings.
