Periodicity Definition:
Repeating patterns in the physical and chemical properties of the elements across the periods of the periodic table.
Cambridge International AS and A Level Chemistry by Ryan Lawrie, Roger Norris
Periodicity Notes:
In chemistry and the periodic table, periodicity is termed as trends or recurring variations in element properties with increasing atomic number. Periodicity is caused by regular and predictable variations in element atomic structure.Mendeleev organized elements according to recurring properties to make a periodic table of elements. Elements within a group (column) display similar characteristics. For example, helium and neon are both fairly unreactive gases that glow when an electric current is passed through them. Lithium and sodium both have a +1 oxidation state and are reactive, shiny metals.
