<span>The notation is not written in the correct order as the 4s subshell should appear before the 3d subshell. </span>The correct order in an electron configuration would be: 1s , 2s , 2p , 3s , 3p , 4s , 3d , 4p , 5s , 4d , 5p , 6s , 4f , 5d , 6p ,.. So, for germanium the electronic configuration should be; 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p²
