This interesting name has two possible sources, the first being as a variant of the nickname or status name 'Free' from the Old English pre 7th Century word 'freo' or 'frig' meaning 'free (born)' i.e., not a serf, not belonging to a lord.lizabeth Fry (1780-1845), was a well known bearer of the name, she became a quaker minister at the age of 29 yrs., and thereafter was tireless in her work as a prison reformer, also inducing the government to regulate the transportation of criminals to Australia.
Plutonium is a transuranic radioactive chemical element with symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized.The element normally exhibits six allotropes and four oxidation states.lutonium-238 has a half-life of 88 years and emits alpha particles. It is a heat source in radioisotope thermoelectric generators, which are used to power some spacecraft.
Plutonium was first produced and isolated on December 14, 1940 by Dr. Glenn T. Seaborg, Joseph W. Kennedy, Edwin M. McMillan, and Arthur C. Wahl by deuteron bombardment of uranium-238 in the 60-inch cyclotron at the University of California, Berkeley.lutonium-238 is synthesized by bombarding uranium-238 with deuterons (D, the nuclei of heavy hydrogen) in the following reaction: In this process, a deuteron hitting uranium-238 produces two neutrons and neptunium-238, which spontaneously decays by emitting negative beta particles to form plutonium-238.
