Electron Configurations of Atoms and Ions The electron configuration of an atom tells us how many electrons are in each orbital. For example, helium has two electrons in the 1s orbital. Therefore the electron configuration of He is 1s^2. Part A What is the ground-state electron configuration of a neutral atom of cobalt? Enter the electron configuration (e.g., [Ne]3s^23p^1). Part B What is the ground-state electron configuration of the oxide ion O^{2-}? Enter the electron configuration (e.g., 1s^22s^2). Part C Which element has the following configuration: [Xe]}6s^25d^14f^1? Enter the symbol for the element.
