Facts about the
Classification of the Element Americium
Americium is classified as an element in the Actinide series as
one of the "Rare Earth Elements" which can located in Group 3
elements of the Periodic Table and in the 6th and 7th periods. The
Rare Earth Elements are of the Lanthanide and Actinide series.
Most of the elements in the Actinide series are synthetic or
man-made.

Facts and Info about
the element Argon - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the
International Union of Pure Applied Chemistry, IUPAC, in 1985
which includes the Americium element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. The Standardised Periodic Table now recognises more periods
and elements than Dimitri Mendeleev knew in his day but still all
fitting into his concept of the "Periodic Table" in which
Americium is
just one element that can be found.
