How is the electron configuration of Cr 3+ Learn this topic by watching Electron Configuration Concept Videos. Cr3+ has 21 electrons, so it's configuration should be. #Cr(VI)# therefore has 18 electrons to distribute . Relevance. The 2+ means that 2 electrons are removed... since 4s^2 (not the 3d shell) is the outermost shell, then those electrons are removed. Did you know? She was a vegetarian and loved olive oil, port wine, and chocolate. The oldest recorded age was 122.
