What are copper ions?

Ion:

• Any molecule or atom with one or more negatively or positively electrical charges is referred to as an ion.

Copper ions :

• Copper ions are copper atoms that consist of 1 or 2 units of positive charges.
• $\mathrm{Copper}\left(\mathrm{I}\right)\mathrm{ion}$ have a $+1$ charge. As copper atoms shed one electron, this occurs. Its formula is${\mathrm{Cu}}^{+}$.
• $\mathrm{Copper}\left(\mathrm{II}\right)\mathrm{ion}$ have a $+2$ charge. As copper atoms shed two electrons, this occurs. Its formula is ${\mathrm{Cu}}^{2+}$.
