Electrons on a periodic table
WebGroups of the periodic table. The s-, p-, and d-block elements of the periodic table are arranged into 18 numbered columns, or groups. The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity. Created by Sal Khan. Webthe number of protons plus the number of electrons electrons in each atom of that element. Your teacher may have demonstrated the reactions that occur between Alkali elements and water. Which one of these elements is the most reactive?
