Same electronic configuration has an ion of Copernicus +1 and Rg
The order of filling the shells with electrons of Copernicus (Cn+): 1s → 2s → 2p → 3s → 3p → 4s → 3d → 4p → 5s → 4d → 5p → 6s → 4f → 5d → 6p → 7s → 5f → 6d → 7p.
On the sub level ‘s’ there might be 2 electrons at most, on ‘p’ - up to 6, on ‘d’ - up to 10 and up to 14 on ‘f’

Oxidation state of Copernicus
Atoms of Copernicus in compounds have an oxidation state of 2, 1.
The oxidation state is the conditional charge of an atom in a compound: the bond in a molecule between atoms is based on the sharing of electrons, thus, if the atom’s charge virtually increases, then the oxidation state is negative (electrons carry a negative charge), if the charge decreases, then the oxidation state is positive.
Oxidation state of an ion Cn+ = 1

Valence of Cn+
Atoms of Copernicus in compounds have valence II, I.
Valence of Copernicus is an ability of an atom Cn to build chemical bounds. The valence is based on electronic configuration of atom: electrons participated in chemical bounds are known as valence electrons. In general the valence is:
The number of possible chemical bounds with other atoms
The valence has no sign.
Quantum numbers Cn 1+
Quantum numbers are defined by the last electron in configuration, for an ion Cn these numbers are N = 6, L = 2, Ml = 1, Ms = -½
