The first electron has the same four quantum numbers as the hydrogen atom electron ( n = 1, l = 0, ml = 0, m s = + 1 2 ). Why is it shorter than a normal address? This tells you that a neutral silver atom will have a total of #47# electrons surrounding its nucleus. First of all the configuration of $\ce{Cu}$ you see has anomalous electron configuration because completely filled or half filled sub shells are more stable than any other configuration and you can see the configuration at last it is $\ce{4s^13d^{10}}$ and the basic configuration is $\ce{4s^23d^{10}}$ so you can see that $\ce{4s}$ is half filled and $\ce{3d}$ is completely filled.
