Co2+ e- configuration is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^7 :) Cr = 24 = 1s² 2s² 2p⁶ 3s² 4p⁶ 4s¹ 3d⁵ 2. 3,090 results chemistry final-urgent electron configuration of Cr3+? 1s2 2s2 2p6 3s2 3p6 4s2 3d1 (giving 1 d-electron) Answer Save. Madame Jeanne Calment was born in France in 1875 and died in 1997. (b) Fe3+ and Mn2+ (c) Fe3+ and Ni2+. The Electronic configuration of Cr and Cu are given below ⇒ 1. [Ar] 452301 O b. Favourite answer. Cr3+ has 21 electrons, so it's configuration should be. 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). BII. 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). #Cr(VI)# therefore has 18 electrons to distribute . Periodic Table Exceptions To Know. KCET 2007: The electronic configuration of Cr3+ is (A) [Ar]3d54s1 (B) [Ar]3d24s1 (C) [Ar]3d34s° (D) [Ar]3d44s2. Answer to: Write the ground state electron configuration for Cr3+. Choose the electron configuration for Cr3+. (d) Sc3+ and Cr3+ Give proper explanation for all the parts 2 See answers Brainly User Brainly User Answer: fe3+ and mn2 because they have same number of … Lv 7. The electron configuration of Cr3+ is O a. The 2+ means that 2 electrons are removed... since 4s^2 (not the 3d shell) is the outermost shell, then those electrons are removed. There is a major exception to the normal order of electron configuration at Cr (#24) and Cu (#29). The oldest recorded age was 122. 94% (397 ratings) Problem Details.
