What is the electronic configuration of Chromium (atomic number = 24)? 3s23p2 b) 4s2 c) 4s3d5 d) 4s3d6
What is the electronic configuration of Chromium (atomic number = 24)? 3s23p2 b) 4s2 c) 4s3d5 d) 4s3d6 Correct Answer Ne
The first 18 electrons fill up principal orbitals 1, 2, and 3 with number of electrons being 2, 8, and 8 respectively. The remaining 6 electrons distribute themselves amongst 4s and 3d such that they all are half filled. This half-filled shell configuration of Chromium is more stable than the rules determined by the Aufbau Principle, hence is preferred over filling up the 4s subshell with two electrons
