The Electronic configuration of Cr and Cu are given below ⇒ 1. The 2+ means that 2 electrons are removed... since 4s^2 (not the 3d shell) is the outermost shell, then those electrons are removed. electron configuration of Cr3 ? electron configuration of Cr3+? Cr3+ has 21 electrons, so it's configuration should be. KCET 2007: The electronic configuration of Cr3+ is (A) [Ar]3d54s1 (B) [Ar]3d24s1 (C) [Ar]3d34s° (D) [Ar]3d44s2. Check Answer and Solution for above q 7 years ago. Relevance. asked by lianne on December 14, 2010; chemistry - … 1 Answer anor277 Nov 1, 2015 #Z# for Cr is 24. #Cr(VI)# therefore has 18 electrons to distribute . I think is Cr: [Ar] 4s1,3d5 but how about Cr+, Cr2+, Cr3+? BII. These electronic configuration are exceptional because electrons entered in 3-d orbitals without filling the 4s orbitals complete. Certain chemicals, after ingestion, can be converted by the body into cyanide. It turns out that the energy the electron configuration that is half-filled, 4s 1 3d 5, and filled orbital, 4s 1 3d 10, has lower energy than the typical filling order, 4s 2 3d 4, and 4s 2 3d 9.This pattern is followed in the 5 th row with Mo (#42) and Ag (#47). Cr is Group 6 and has six valence e⁻s; its electron configuration in the gas phase as a neutral atom is [Ar] 3d^5 4s^1 ( I can explain this if you wish). To write the configuration for the Manganese ions, first we need to write the electron configuration for just Manganese (Mn). Please explain? She was a vegetarian and loved olive oil, port wine, and chocolate. Answer to: Write the ground state electron configuration for Cr3+.
