electronic-configuration so we'd expect the electron config for copper to be [Ar]3d^9 4s^2 but the element is more stable by having the 3d orbital full than the 4s so thats why the electron config is [Ar]3d^10 4s^1. Now sometimes the noble state is written as $\ce{[Ar] 3d^10 4s^1}$ or as $\ce{[Ar] 4s^2 3d^9}$. Solved: The expected electron configuration for copper should be [Ar]4s^2 3d^9. Copper (Cu) has two valences Cu I (cuprous) has one valence electron and Cu II (cupric) has two valence electrons. L shell – 6 electrons. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. The electronic structures of the d-block elements are shown in the table below. Most chemistry books and chemistry teachers try to explain the breaks in the pattern at chromium and copper - but not very convincingly. 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. Copper typically forms a bluish green solution. Copper is the second example, after Chromium, of elements that don’t rigidly follow the simplest version of the rules for filling electron orbitals learned in introductory chemistry. The outer electron governs their properties and that electron is in the same sort of orbital in both of the elements. Megna Patel 1I Posts: 24 Joined: Fri Sep 25, 2015 10:00 am.

The electron configuration of copper is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 3d 10. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. However, notice that 1s 2 2s 2 2p 6 3s 2 3p 6 is the configuration for Argon, a noble gas. The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar] 3d 10 4s 1. Copper, and chromium as well, are two exceptions. Electronic configuration of Copper, with atomic number 2 9 = 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 1 3 d 1 0 . Copper is a chemical element with symbol Cu and atomic number 29. I thought it was the 3d electron, but someone else said it was the 4s electron. To use electron affinities properly, it is essential to keep track of sign. Copper's electron configuration might be predicted to be 3d94s2. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Electronic configuration of Chromium, with atomic number 2 4 = 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 1 3 d 5.
