Homework Equations None The Attempt at a Solution Since Gd has 64 electrons, I would assume that the electron config. Writing electron configuration worksheet answer key. Electron Configurations are an organized means of documenting the placement of electrons based upon the energy levels and orbitals groupings of the periodic table.. I understand how the configuration was formed, but why is the configuration different? The ground state electron configuration of ground state gaseous neutral lanthanum is [Xe].5d 1.6s 2 and the term symbol is 2 D 3/2. Homework Statement What is the electron configuration for Gd?
