What is cu2+ ion name?

The Cu²⁺ ion is a copper cation. A cation is a positively charged ion that is formed when an atom loses one or more electrons. The Cu²⁺ ion has a charge of 2+, which means that it has lost two electrons from its outermost energy level. The Cu²⁺ ion is also known as the copper(II) ion.

Copper(II) is a term used to describe the state of oxidation of copper in which it has an oxidation number of +2. Copper can exist in several different oxidation states, depending on the number of electrons it has gained or lost.

The Cu²⁺ ion is the most common form of copper in aqueous solution, and it is often used to prepare copper(II) salts, such as copper(II) sulfate and copper(II) chloride. Copper(II) compounds are used in a variety of applications, including in the production of pigments, catalysts, and herbicides.
