How many electrons does copper III lose or gain?

Question

How many electrons does copper III lose or gain to become a copper ion. Is it a caption or an anion?

pisgahchemist · Answer

There is no Cu^3+(aq) ion....

The few compounds in which copper(III) exists usually involve other metals in insoluble oxides. (https://en.wikipedia.org/wiki/Copper#Copper(III)_and_copper(IV))

Roger the Mole · Answer

Copper III is already a cation. An atom of metallic copper loses 3 electrons to become copper III.

Lôn · Answer

Cu -----> Cu3+ because it LOSES 3 electrons.

As the ion is attracted to the cathode (-)  it is called a cation (NOT caption)
