Ion exchange of rare earth elements in the presence of chelating ligands on anion exchangers is still a poorly studied field. However, the papers published during the last few years show particular applicability of anion exchangers to this end.
Abbreviated notation: since the last complete level is the number 3s² 3p⁶, you use the noble gas of the period 3, which is Ar, and the configuration is: [Ar] 4s² 3d². b) Cu²⁺ Z = 29; Number of protons: 29; Number of elecrons of the neutral atom: 29; Charge of the ion: + 2; Number of electrons of the ion: 29 - charge = 29 - 2 = 27.
