Question

If copper loses its two electrons then it can be written as____?​

Answer 1

Answer:

Copper(II) has an oxidation state of +2; the elemental metal has an oxidation state of 0. Gain of electrons is a reduction reaction. In a redox reaction, the reactant that loses electrons (is oxidized) causes a reduction and is called a reducing agent. ... Cu2+ ion gains two electrons (is reduced) to form copper metal.
