How do you write Copper II?
Copper(II) oxide is a metal oxide that has the formula CuO. It has an ionic structure.
Why do we write Copper II?
Copper(II) has the Roman numeral II because it loses two electrons forming Cu+2. Oxygen gains two electrons forming O-2. Since these ions are plus and minus 2, they cancel each other out, which is a requirement for an ionic compound.
What is the difference between copper and copper I?
Copper 1 vs Copper 2 Copper 1 is the +1 oxidation state of copper. Copper 2 is the +2 oxidation state of copper. Copper 1 is formed by the loss of one electron from a copper atom. Copper 2 is formed by the loss of two electrons from a copper atom.
