What irregularities are observed in the electron configuration of chromium and copper?
Answers
Answer:
Explanation:
There are two main exceptions to electron configuration: chromium and copper. In these cases, a completely full or half full d sub-level is more stable than a partially filled d sub-level, so an electron from the 4s orbital is excited and rises to a 3d orbital.

Answer:
The arrangement of electrons around the nucleus of a specific atom or molecule is known as its electronic configuration. Protons, neutrons, and electrons are the main components that make up an atom. There is the same number of protons and electrons in a neutral atom.
Explanation:
The electronic configuration of chromium is [Ar] 3d⁵ 4s¹
The electronic configuration of copper is [Ar] 3d¹⁰ 4s¹.
The d-orbital is half filled in chromium whereas the d-orbital in copper is fully filled. Such type of filled orbitals leads to the maximum stability of the element.
If the s-orbital is completely filled and d-orbitals are partially filled then it does not leads to the stability of the element. It becomes unstable.
Hence, the irregularities observed in the electronic configuration of chromium and copper are the maximum stability of the orbitals.
