Why is the electron configuration of copper AR 4s1 3d10 and not Ar 4s2 3d9?
Copper has atomic number of 29 which means it has 29 electrons and 29 protons. Argon is the noble gas with 18 electrons. As completely filled d-shell is more stable in nature. Hence, one electron from the 4s shell goes into the d-orbital so the copper atom can attain stability.

What is the element with electron configuration AR 4s2 3d10 4p1?
The element is gallium (Ga), which has the atomic number 31.
What element has the electron configuration AR 4s2 3d10 4p4?
selenium element
The obtained atomic number 34 corresponds to the selenium element. Hence, the neutral element that has the electron configuration of [Ar]4s23d104p4 [ A r ] 4 s 2 3 d 10 4 p 4 is Selenium.
Which is more stable configuration and why 4s2 3d9 or 4s1 3d10?
Therefore one electron from 4s2 is removed making Cr [Ar] 3d5 4s1. Same is the case with Cu, it would be [Ar] 3d9 4s2, but again it would be more stable if the d shell is completely filled with 10 electrons, instead of 9. Therefore and electron from s is removed making Cu it [Ar] 3d10 4s1.
Why is copper 4s1 not 4s2?
Copper is, according to the periodic table, [Ar]3d9 4s2, but it wants to become more stable with a completely filled 3d subshell, so one electron from 4s moves to 3d, making it [Ar]3d10 4s1.

Why is CU 3d10 4s1?
Re: Chromium and Copper Same is the case with Cu, it would be [Ar] 3d9 4s2, but again it would be more stable if the d shell is completely filled with 10 electrons, instead of 9. Therefore and electron from s is removed making Cu it [Ar] 3d10 4s1.
What is the electron configuration for zinc (Zn) 3d10?
Since Zinc is the last element located on the 3 d group, it will be 3d 10. However, if it were to be Ge 3+, the new configuration would read [Ar] 4s1 3d10, because now we are removing 3 electrons and the element we are describing is Copper (Cu).
What is the electron configuration of [Ar] 3d10 4s2 4p2?
So the electron configuration is [Ar] 3d10 4s2 4p2 in the ground state. Ge can show oxidation state from -4 to +4 while the +2 and +4 are the most common.
What is the electron configuration of nickel (N)?
Originally Answered: Electron configuration of Nickel is [Ar] 3d8 4s2 or [Ar] 3d9 4s1. Why doesnt the electrons in the s-orbital move to the 3d-orbital so it can be fully filled? Nickel is 3d8 4s2. The 4s orbital is fully occupied even though it is higher in energy.
What is the right orbital configuration for iron (Fe)?
The right orbital configuration for iron (Fe) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 because it has been written according to Afbau’s principle. Also called his diagonal rule. In writing the electron configuration, you must fill in electrons into orbitals of low energy levels before moving on to fill orbitals of higher energy levels.
