The copper is losing 2 electrons to become a cation. How would you describe this process @LuhVee1 ?

Remember,

 $\underbrace{\Large OIL ~RIG}_{\Large\text{oxidation is losing  -   reduction is gaining}}$. 

Oxidation is the loss of electrons while reduction is the gaining of electrons. 

$\sf Cu \rightarrow Cu^{2+}+2e^-$
Cu is losing two electrons. So what kind of a reaction is this?
