Answer 1

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."
