Hydrogen only has one electron and therefore has a configuration of s .In order to fill it’s energy level it only needs one more electron obtain a full outershell s .This is why we only put two electrons on Hydrogen atoms when drawing Lewis structures..Noble gas configuration. Electron configurations for the first period. Electron configurations for the third and fourth periods. Electron configurations of the d transition metals. Practice Electron configurations. This is the currently selected item. Paramagnetism and diamagnetism..Electron Configuration Notation shows the arrangment of electrons around the nucleus of an atom. helps chemist understanding how elements form chemical bonds. can be written using the period table or an electron configuration chart. How to Write the Electron Configuration for Carbon..Electron configurations describe where electrons are located around the nucleus of an atom. For example, the electron configuration of lithium, ss, tells us that lithium has two electrons in the s subshell and one electron in the s subshell..
