A similar result is found for the alkaline earth metals in group 2 (Be, Mg, Ca, etc.) Each of those elements has an electron configuration ending in s 2. For example, in group 1 (the alkali metals) the electron configurations are:Įach of these elements has an electron configuration that ends with an s-orbital containing one electron: 2s 1, 3s 1, 4s 1, etc. Within a group we found that the electron configurations always ended with the same type of orbital with the same number of electrons. In this activity we practiced writing the ground state electron configuration for elements in the same column, or group, in the periodic table.
