Answer to: Write the ground state electron configuration for Cr3+. 94% (397 ratings) FREE Expert Solution. Favourite answer. 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). The 2+ means that 2 electrons are removed... since 4s^2 (not the 3d shell) is the outermost shell, then those electrons are removed. 1 Answer. Please explain?
