The electron configuration of copper is: [Ar]4s13d10.
It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.

Cu+3 reported formally in 2007. Cu 1 e's in 4S and 10 e's in 3D Cu+3 0 e's in 4S and 8 e's in 3D LFSE suggets the existence of Cu+3.
The electronic configuration for aluminum is 1s22s22p63s23p1 .
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
