Why is the electron configuration for copper 3d10 4s1 - shouldn't it be 3d9 4s2?

The actual for copper is 3d10 4s1. 3d10 4s2 is Zinc. 3d8 4s2 is Nickel. Among these Transition Metals [in this book], 3d9 4s2 is not listed. Help pls.

Why electronic configuration of copper is 1s2 2s2 2p6 3s2 3p6 4s1 3d10 and why not 1s2 2s 2p6 3s2 3p6 4s2 3d9?

Because having a half-filled s sublevel, such as 4s1, followed by a filled d sublevel, such as 3d10 is more stable than having a filled s sublevel, such as 4s2, followed by a d sublevel that is almost full, such as 3d9, which is very unstable.

the transition elements which have anomalous electron structure in period four exist in group number?

Cu has an anomalous electron configuration. Cu = 1s2 2s2 2p6 3s2 3p6 4s1 3d10, it does not follow the usual pattern. In this case, the 3d subshell is filled before the 4s, which usually happens in the reverse order (1s2 2s2 2p6 3s2 3p6 4s2 3d9).
