In fact it isn't. Copper (II) ions are stable wrt copper (i) ions. Although this is apparently contradictory to the electronic structure. This anomaly has been attributed to the Jahn-Teller effect which is the lengthening of the axial ligand bonds in a transition metal complex.

Copper has 29 protons and 29 electrons. If it gains one (Cu+1) then it will have 30 electrons which gives it a full d orbital. If it gained 2 then it would want to lose one and be very unstable until it does.

Cu(I) has a stable electron configuration i.e. the electrons occupy the valence shell completely.
Cu(II) has one electron short of a complete valence shell.

ok when an atom goes positive it doesn't gain electrons it looses them. Cu1 has more protons than electrons so they come in close and the arrangement becomes more stable

The outer electrons are closer to the nucleus and so harder to lose which makes cu(I) more stable

maybe lack of ionization energy required to break off the other electron.

kevster is correct.
I couldn't answer because I couldn't think of a good reason. My inorganic is a little weak, it seems.
