The definition of f-block elements, classification as #lanthanides and #actinides been explained with illustrations.  Electronic configurations of these materials, decrease in sizes of f-block elements due to #lanthanide & actinide contractions is explained using poor shielding of f-electrons. Applications of lanthanides in flints, phosphors and Mischmetall alloys, the specialty of actinides in nuclear reactors as fuels have been given.  #lanthanideContraction, #f-blockElements, #ActinideContraction,
