What is the longhand configuration for Chromium?
1s2,2s2,2p6,3s2,3p6,3d5,4s1
What is the noble gas configuration of chromium?
The noble gas configuration of chromium is [Ar] 3d5 4s1. It is written this way because the electron configuration of argon (1s2 2s2 2p6 3s2 3p6) is the closest noble gas configuration to chromium, with 3d5 4s1 representing the additional electrons in the chromium atom.
What are three examples of elements with unpredictable electron configurations?
Chromium: Chromium typically forms a half-filled d5 configuration (4s1 3d5) instead of a fully-filled d4 configuration (4s2 3d4) due to the increased stability associated with the half-filled d orbital. Copper: Copper prefers to have a full d10 configuration (4s1 3d10) instead of a partially filled d9 configuration (4s2 3d9) as it increases stability. Silver: Silver can have an electron configuration of [Kr] 4d10 5s1 instead of the expected [Kr] 4d9 5s2 due to the stability associated with the fully-filled 4d orbital.
What is the the noble gas configuration of chromium?
[Ar]3d54s1
What kind of minerals are chromium copper and iodine considered?
Chromium, copper, iodine, and selenium are trace minerals.
What are two elements with ground-state electron configurations that are well-known exceptions to the Aufbau principle?
Chromium and copper are well-known exceptions to the Aufbau principle. Chromium has an electron configuration of [Ar] 3d5 4s1 instead of the expected [Ar] 3d4 4s2, and copper has an electron configuration of [Ar] 3d10 4s1 instead of the expected [Ar] 3d9 4s2.
Which description of electron configuration applies to atoms of potassium chromium and copper?
Potassium: [Ar] 4s^1 Chromium: [Ar] 4s^1 3d^5 Copper: [Ar] 4s^1 3d^10
What is the electron configuration for Chromium and Chromium II is?
The electron configuration for Chromium (Cr) is [Ar] 3d^5 4s^1. The electron configuration for Chromium II (Cr^2+) is [Ar] 3d^4.
What element has an electronic configuration of 1s2s2p3s3p4s3d?

Electrons in chromium?
Chromium has 24 electrons. Its electron configuration is [Ar]3d5 4s1. This configuration allows for the half-filled d orbital, which gives chromium additional stability.
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 electron configuration of a chromium atom in its 2 oxidation state?
The electron configuration of a chromium atom in its 2 oxidation state is Ar 3d4 4s0.
