Copper #2

Copper #2

The key difference between copper 1 and copper 2 is that copper 1 is formed by the loss of one electron from a copper atom whereas copper 2 is formed by the loss of two electrons from a copper atom. Copper is a transition element that can be found in the d block of the periodic table of elements. Copper(II) has the Roman numeral II because it loses two electrons forming Cu+2. Oxygen gains two electrons forming O-2. Since these ions are plus and minus 2, they cancel each other out, which is a requirement for an ionic compound. The formula for copper(II) oxide is CuO. IUPAC name. Copper(II) oxide. Other names. Cupric oxide. When one of the 4s electrons is moved to the 3d sub orbitals there are 10 3d electrons completely filling the 3d sub orbitals, making it more stable. ... Copper becomes a + 2 ion by losing both of the 4s electrons. Losing the two 4s electrons makes copper more stable.

Scrap copper #2 tubing is different than copper number one tubing in a many ways. The most noticeable difference between the two classifications of scrap copper is that copper #2 tubing does not have a shiny look to it.
