What happens to chromium that makes it an exception to the order of filling orbitals?
Chromium is an exception to the electron configuration pattern because electrons will occupy subshells until half-full and THEN start pairing up. We would expect chromium to follow the trend after Vanadium: V 'Ar' 3d3 4s2- All the subshells are either full or half full (or empty) Cr 'Ar' 3d4 4s2- this is the configuration expected- but this is less STABLE for the atom. The true configuration is: Cr 'Ar' 3d5 4s2 This is so the d block is completely half full as is the s block meaning it is more stable. This links with the fact that electrons occupy subshells until half full and THEN start pairing up.
Why copper and chromium has exceptional configuration?
i dont know you should have study
What is ar 3d54s1?
Perhaps the electronic configuration of Chromium? Ar for argon, argon has 18 electrons. Electronic configuration of argon can be written as 1s22s22p63s23p6. Electronic configuration of chromium is 1s22s22p63s23p63d54s1. As you can see you can just replace that long chain of figures in front of 3d54s1 with just Ar. Hence, [Ar]3d54s1.
What is the longhand configuration for Chromium?

What is the configuration for chromium?
Chromium has atomic no. of 24. Its electronic configuration is 1s22s22p63s23p64s13d5 . It should be 4s23d4 but it is not because the half filled d-sub shell provides extra stability to chromium atom.
What is the noble configuration of chromium?
[Ar]3d54s1
What is the electronic configuration of chromium?

What is the electron configuration for Chromium and Chromium II is?
1s2 2s2 2p6 3s2 3p6 4s1 3d5
What is the electron configuration for Cr4?
Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 3d^5 Short-hand version: [Ar] 4s^2 3d^4 Note: The "^" symbol means the the following number is in the form of a superscript. The above is wrong because Cr is an exception. the actual answer is [Ar] 4s^1 3d^5 because it has a half filled subshell

Electron configuration of chromium II ion?
The electronic configuration of chromium is 1s2 2s2 2p6 3s2 3p6 3d5 4s1.
How the electron configuration of chromium is used to strengthen alloys?
Chromium has a half filled D orbital so is stable.
