Krypton and argon both have 8 valence electrons. This is true of all noble gases except helium, which has only 2 valence electrons.
In the shorthand method for showing electron configuration, the noble gas preceding the element is used to indicate the core electrons (inner shell electrons), while the valence electrons are indicated by the remaining electron configuration. For example, the electron configuration of potassium (K) can be written as [Ar] 4s¹, where [Ar] represents the noble gas core configuration (argon's electron configuration).
The electron configuration for germanium is [Ar]3d10.4s2.4p2.
The electron configuration of calcium using noble gas notation is [Ar] 4s2. This notation indicates that calcium has the same electron configuration as argon ([Ar]) up to the 18th electron, and then adds two electrons to fill the 4s energy level.
The noble gas configuration for cobalt (Co) is [Ar] 3d7 4s2, where [Ar] represents the electron configuration of argon. This notation indicates that cobalt has the same electron configuration as argon, with an additional 3d7 4s2 electron configuration specific to cobalt.
The electron configuration of Cu+1 is [Ar] 3d10 4s1. When copper loses one electron to become a +1 ion, it loses the 4s electron first, followed by one of the 3d electrons to attain a stable electron configuration.
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, Cl (chlorine) and Ar (argon) do not have the same electron configuration. Cl has the electron configuration 1s2 2s2 2p6 3s2 3p5, while Ar has the electron configuration 1s2 2s2 2p6 3s2 3p6. Ar has a full outer shell, making it a noble gas, while Cl is a halogen with one electron short of a full outer shell.

Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
In the shorthand method for showing electron configuration, the noble gas preceding the element is used to indicate the core electrons (inner shell electrons), while the valence electrons are indicated by the remaining electron configuration. For example, the electron configuration of potassium (K) can be written as [Ar] 4s¹, where [Ar] represents the noble gas core configuration (argon's electron configuration).
The electron configuration for germanium is [Ar]3d10.4s2.4p2.
The electron configuration for V3 is Ar 3d2.
The electron configuration of V3 is Ar 3d2.
The electron configuration of calcium using noble gas notation is [Ar] 4s2. This notation indicates that calcium has the same electron configuration as argon ([Ar]) up to the 18th electron, and then adds two electrons to fill the 4s energy level.
The abbreviated electron configuration of cobalt is [Ar] 3d7 4s2.
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.
