The truncated periodic table shown above provides the orbital electronic by their electron configurations. are exceptional in that .The electron configuration of chromium is What is the electron configuration for a nitride ion? What is the electron configuration of copper? .SOCRATIC Why do the electron configurations of chromium and copper seem to disagree with what is What is the electron configuration of copper?.When we write the electronic configuration of Cr as per the ‘Aufbau principle’ the d orbital contains electrons and the s orbital contains electrons..
Exceptional electronic configuration
