What is a lanthanide element?
Lanthanides are any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57 - 71). With scandium and yttrium, they make up the rare earth metals. Their atoms have similar configurations and similar physical and chemical behaviour; the most common valences are 3 and 4.
How lanthanide contraction controls the atomic sizes of elements of 6th and 7th periods?
From moving from left to right the atomic size decreases.In case of Lanthanides lanthanide contractions occur and this results from the poor shielding of nuclear charge by 4f electrons,the 6f electrons are drawn towards the nucleus ,thus resulting in smaller atomic radius.
