Losing Valence Electrons to Form Ions

Postby Karishma_1G » Sun Oct 28, 2018 11:24 am

Hi, I was wondering why copper can lose two electrons when it only has one electron in its outermost shell (4s). Wouldn't the ionization energy be extremely high to remove an electron from the 3d subshell?

It is usually on a case-by-case basis. For example, CuCl2 is more stable than CuCl, but CuI is more stable than CuI2. This is due to the specific physics of the electrons in the 3d subshell.
