Answer:
+1
Explanation:
2,8,18 is structurally stable as valence electrons are filled completely
this represents electronic configuration of copper
in basis of orbital concept configuration may be written as
1s² , 2s² 2p⁶, 3s² 3p⁶ 4s¹,3d¹⁰
as oxidation state is determined by valence electrons
oxidation state of element is +1 as it can easily donate 1 electron and become stable
