===Plutonium belongs to the Actinide family. The actinide series is as one of the “Rare Earth Element." Plutonium is made out of medal. The symbol for plutonium **Pu. Plutonium’s atomic number is 94. The number of protons is 94, the number of neutrons is 150, and the number of electrons it has is 94. Its melting point is 640 degrees C and 1184 degrees F. The boiling point for plutonium is 3228 degrees C and 5842 degrees F. The normal phase of plutonium is solid. The cost for Plutonium is 4,000 for per gram. The atomic mass is 244 for plutonium. The color is slivery with yellow tarnish when slight oxidized.** ===

===Plutonium was discovered by nuclear chemist Glenn T. Seaborg and his colleagues Joseph W. Kennedy, Edwin M. McMillan, and Arthur C. Wahl, in 1941 at the University of California - Berkeley. However they announced the discovery until 1948. The origin of the name of plutonium is named after the planet Pluto.=== ===Plutonium is used for bombs, nuclear reactors, and man-made. Plutonium also uses Radiological weapons, poison, electrical power generation. Plutonium can be extremely poisonous. Serious medical problems or even death if it gets in your body. Inhaled plutonium can remain in your lungs for 500 days. Also the radiation from plutonium can harm the future generations.=== v ****It is very sensitive to changes in the temperature, pressure, and chemistry. ** v **Scientists now know that very small amounts of plutonium occur in the Earth's crust. ** v **The plutonium that is formed can be removed from the reactor. ** v
