The electronic configuration od Cu is [Ar] 3d10 4s1
This is an exception to the aufbau principle which would predict [Ar] 3d9 4s2.
The electron configuration of Cu2+ is [Ar]3d94s0.
well, its quite obvious.orbital notation is the notaion of orbitals and electron configuration notation is the configuration of electrons?!??!?!kthanksbye
There is 1 unpaired electron in Copper (Cu)
The electron configuration of uranium is (short): [Rn]5f36d17s2.
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.
Orbital notation shows how the electrons are arranged in the orbitals of the sublevels. Electron configuration shows only how many electrons are in each sublevel.
[XE] I think or is this the electron configuration
Electron configuration of helium: 1s2
[He] 2s1
1s22s22p63s23p64s23d104p65s24d105p66s24f145d10
[Ar]4s23d104p2
Electronic configuration of hafnium: [Xe].4f14.5d2.6s2
