Fe1, Fe2, Fe1million are fine, since only the first two letters are used
by function atomic_number. There is however a problem for all one-letter
elements: B C F H K I N O P S V W Y. For the time being, just use O as
species label instead of O1 (you can change it in the data.xml file).
Not sure specifying sn atomic symbol as ' O1' will work.
