The atomic number and the ground state configuration of the next alkali metal after Francium is to be predicted. Concept Introduction: The elements that belong to the group IA (1) of the periodic table are known as alkali methods. They are very reactive and electro positive in nature. The atomic number of an element in this group can be obtained by the addition of the magic number to its previous element. The addition from top to bottom is done in the according to the series 2 , 8 , 8 , 18 , 18 , 32 , 32 . To determine: The atomic number of the alkali metal that would come after Francium and its ground-state electronic configuration.
