•The groups in the Periodic Table are numbered from 1 to 18. •Elements in the same group have the same number of valence electrons. •Example: Sodium and potassium are both found in group 1 which means that they both have 1 valence electron KMP/ChemUnit/SK017-10/11 4 4 Group number = number of valence electron (if the element is in block s and d) OR
Sodium (Na) and potassium (K) are in the same group on the periodic table. Based on their locations, which statement about sodium and potassium is true? Why are the elements fluorine, chlorine and iodine placed in the same group of the Periodic Table? They have the same number of electrons in their outer shell.
