We can just decide on a scheme ourselves, can't we?
I propose to use
Cl (the chemical symbol) for the atomname, as this is also done for more
complex ions, like sulphate.
Cl- for the residue name, because that's what it is.
The type name we could use, in analogy to protein, chloride, so the full
name of the species.
