Tool to convert electronic configuration of atoms. Electronic configuration of atoms or molecules is a notation describing the position of electrons by orbitals, by couples of digits and letters.

From the current list of atomic configurations known, it is necessary to replace the configuration by the atomic symbol in the periodic classification of Mendeleiev (the atom Ne, Ar, Kr, Xe ou Rn is optional)
Example: (Ar) 3d2 4s2 = Titane = Ti
To convert to atomic number, use the periodic classification of elements.
For each symbol of a detected chemical element, it is converted to its ground state electronic configuration notation, by orbital layers. (The layers of Ne, Ar, Kr, Xe or Rn atoms are ignored when writing)
Example: C = Carbon = 1s2 2s2 2p2
Example: Fe = Iron = [Ar] 3d6 4s2
Example: Cl = Chlorine = [Ne] 3s2 3p5
Example: Cu = Copper = [Ar] 3d10 4s1
