Step 3: The highest principal energy level is 4 so the valence electrons in it should be 2 but it is a transition metal. So, it also includes all the electrons outside the noble gas configuration as the valence electrons and therefore there are 8 valence electrons in iron.

Chemical reactivity Zinc exhibits only the +2 oxidation state. It can give up two electrons to form an electrovalent compound; e.g., zinc carbonate ZnCO3. It may also share those electrons, as in zinc chloride, ZnCl2, a compound in which the bonds are partly ionic and partly covalent.

The element copper has 11 valence electrons, distributed amongst the outermost d and s orbitals. These electrons are the ones that engage in chemical reactions that involve photons corresponding to visible light. ... Copper's valence shell configuration is responsible for it's premier conductivity among metals.

All of the electron orbital in the first three energy levels are filled. The 4s sub level is also filled and the 3d sub shell is filled. There are no unpaired electrons in Zinc. Zinc is unusually stable because of the lack of unpaired electrons.
