Krypton and argon both have 8 valence electrons. This is true of all noble gases except helium, which has only 2 valence electrons.
The electron configuration of Cu2+ is [Ar]3d94s0.
Cobalt(II) electron configuration is [Ar]3d7.
The electron configuration for germanium is [Ar]3d10.4s2.4p2.
[Ar]3d104s24p6
The electron configuration of nickel is: [Ar]4s13d9 (four electron shells).
Krypton has 8 valence electrons.The electron configuration is: [Ar]3d10.4s2.4p6.
Short answer: [Ar] 3d10 4s2 4p3 OR 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3
No. No two elements have the same electron configuration.
The electron configuration of Cu2+ is [Ar]3d94s0.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.

The electron configuration for germanium is [Ar]3d10.4s2.4p2.
Cobalt(II) electron configuration is [Ar]3d7.
The electron configuration of arsenic is: [Ar]4s23d104p3.
[Ar]3d104s24p6
Valence electron configuration of zinc, abbreviated. [Ar] 4s2 3d10 Zinc's oxidation state is 2, so that 4s2 represents the valance electrons though they are at a lower energy level and the 3d10 gives you the full outer electron configuration.
Titanium has the valence electron configuration of [Ar] 3d2 4s2. This means that Ti has 2 valence electrons, lying in the 4th s orbital. Note the relationship between the d-orbital and valence electrons is more complicated, but they are not regularly considered valence electrons.
