WebbThe periodic table is the table that indexes all chemical elements. It is arranged in order of atomic size (Hydrogen, then Helium, then Lithium, etc.) which is determined by the number of protons in the element. The table is subdivided into periods (rows) and groups (columns) of elements that share common characteristics, hence the name "periodic". WebbIn Period 3, sodium with 11 protons is the least electronegative element, and chlorine with 17 protons is the most electronegative element.
