Facts about the
Definition of the Element Plutonium
The Element Plutonium is defined as...
A radioactive metallic element similar chemically to uranium that
is formed as the isotope 239 by decay of neptunium and found in
minute quantities in pitchblende, that undergoes slow
disintegration with the emission of an alpha particle to form
uranium 235, and that is fissionable with slow neutrons to yield
atomic energy.
Interesting Facts
about the Origin and Meaning of the element name Plutonium
What are the origins of the word Plutonium ?
The name originates from the the planet Pluto.
Facts about the
Classification of the Element Plutonium
Plutonium 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 Plutonium 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. Plutonium was discovered by Dr. Glenn T. Seaborg, Edwin M.
McMillan, J. W. Kennedy, and A. C. Wahl in 1940 in the USA. 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
Plutonium is
just one element that can be found.
