2 Definition The definition of periodicity is the repetition of similar properties in chemical elements, as indicated by their positioning in the periodic table. The definition of periodicity is the repetition of similar properties in chemical elements, as indicated by their positioning in the periodic table. Simple Explanation: This means that periodicity is the fact that some elements in the periodic table have the same properties as other elements in the same column of the periodic table. Simple Explanation: This means that periodicity is the fact that some elements in the periodic table have the same properties as other elements in the same column of the periodic table.

3 Periodic Table of the Elements

4 Relation to Periodic Table The black arrows drawn onto the periodic table show that all of the elements in these columns have similar properties, as opposed to elements in rows having similar properties. The black arrows drawn onto the periodic table show that all of the elements in these columns have similar properties, as opposed to elements in rows having similar properties.

5 Inconsistencies This property doesnt change for all the elements in columns on the periodic table, but it does change for a few. For instance, hydrogen and francium are in the same group (s 1 ) but hydrogen is a gas and francium is a solid. However, this property stays the same for most elements on the periodic table, for instance columns s 2 and p 2 have all the elements in the same form.
