no false 
Cuprous  ion
(Cu(I),  Cu+)   has   completely   filled   d-orbitals   with   10
electrons (3d10), while the cupric ion (Cu(II), Cu2+) has only
9 electrons  in  the  d  orbitals,  (3d9)  with  one  electron  being
unpaired.    Consequently    bivalent    copper    (Cu(II))    is
paramagnetic and represents the most stable oxidation  state
of copper."
