Z=29
So 29 electrons in non ionized ste
IMPORTANT
this the configuration of the electronic shell of copper
Cu 1s22s22p6 3s33p6 4s13d10
there is an exception normally you should have 4s23d9!!
a complete subshell is more stable!

Electrons per shell are 2, 8, 18, 1. So, if you add them all you will get 29. You have just to look at the atomic number in periodic table.
