Oxidation state of Palladium
Atoms of Palladium in compounds have an oxidation state of 4, 2, 0.
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 Pd4+ = 4

Valence of Pd4+
Atoms of Palladium in compounds have valence IV, II.
Valence of Palladium is an ability of an atom Pd 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 Pd 4+
Quantum numbers are defined by the last electron in configuration, for an ion Pd these numbers are N = 4, L = 2, Ml = 3, Ms = -½
