Well, first, Copper has 29 electrons and 29 protons, and in nature it has two isotopes.

Electrons per Energy Level: 2, 8, 18, 1.

Here is the electron configuration of copper:

(1s^2) (2s^2 2p^6) (3s^2 3p^6 3d^10) (4s^1)

>>> Also, the matter is sort of interesting, when you consider the electronic configuration of transition metal elements. They are characterized as having full outer sub-orbitals and the second outermost d sub-orbitals incompletely filled. With the exception of .. Copper! The thing is, that here, a completely full or half full d sub-level is more stable than a partially filled d sub-level. I recall something similar being the case with chromium, and that anyways, an electron configuration happens because the overall configuration is lower in energy than any alternative. Sometimes the reasons are obscure
