What is ionic charge of copper? Explanation: Copper (I) ions have a 1+ charge. This happens when copper atoms lose one electron. Its formula is Cu+ .
Why does copper have a 2+ charge? Because the charge field density of the copper atom’s electron cloud moves a 4s into 3d. In zinc it’ll add a second electron to 4s. Welcome to chemistry. Thus, copper certainly does have 2 valence electrons it can lose, giving it an oxidized state of 2+.

Which element is reduced in copper silver nitrate?
Silver nitrate (AgNO3) reacts with copper (Cu) to form copper(II) nitrate (Cu(NO3)2) and silver (Ag). This can be called a redox reaction because silver nitrate is reduced and copper is oxidized. This can also be called a single replacement reaction because copper replaces silver in the substance silver nitrate.
