Copper,  which is a d block element, is named as cuprous or cupric based on the electronic configuration. The main difference between cuprous and cupric is that  cuprous is copper +1 cation  whereas cupric is copper +2 cation. When copper is reacted with oxygen, two stable compounds Cu2O and CuO form.   Copper Oxide  is the inorganic compound with the formula CuO (Figure 1) also known as  ‘cupric oxide’ . In this form, Cu is in the form of Cu+2 and the electron configuration of the Cu changes from [Ar]3d104s1 to [Ar]3d94s0. It is known as tenorite as a mineral (Figure 2). CuO can be obtained by using pyrometallurgical processes. Figure 1: Copper Oxide (CuO) Powder Cuprous Oxide  is the other stable compound of Copper with formula Cu2O. In this form, Cu is in the form of Cu+1. Its electron configuration changes from [Ar]3d104s1 to [Ar]3d104s0 so it is more stable compared to copper(II) oxide. CuO(Figure 3) is generally obtained via the oxidat...
