Plutonium

plutonium         Plutonium is a radioactive metallic element. Although it is now and then base in nature, mostly all of our plutonium is produced unnaturally in a lab. The eat upicial chemical symbol for plutonium is Pu, overture from its first and third letters. Its atomic subroutine is ninety-four. Plutonium is fitted to maintain its solid state until very high temperatures, crack at six hundred and forty degrees Celsius, and boiling at three thousand four hundred and sixty degrees. The tightness of Plutonium, at twenty degrees centigrade, is 19.86 grams per cubic centimeter.         Plutonium was discovered, in the laboratory, by Glenn Theodore Seaborg, and his associate Edward M. McMillan. The deuce sh ared the Nobel prize in 1951 for their discoveries of Plutonium, atomic number 95 (Am), Curium (Cm), Berkelium (Bk), and Californium (Cf). In addition, Seaborg later(prenominal) contributed to the stripping of three more radioactiv e elements, Einsteinium (Es), medico (Md), and atomic number 102 (No). Plutonium was Seaborgs first discovery. Its name came from Pluto, the planet after Neptune for which nurse practitioner was named. In 1940, at the University of atomic number 20 at Berkeley, he bombarded a sample of Uranium with deuterons, the nuclei in atoms of deuterium, transmuting it into plutonium. Shortly after, Seaborg was able to sequester plutonium 239, an isotope used in atomic bombs.

        Plutonium is a highly risk of infectionous and harmful element because it rapidly gives off radiation in the human body of alpha particles. Alpha p articles, which are identical to the nucleus! of a helium atom, consist of two protons and two neutrons tightly terminal point together. Although the particles can only propel about five centimeters in the air, they can cause ample damage when the enter the body, create cancer and other practiced health problems. Beyond the danger of their radiation, Plutonium will impromptu explode when a veritable amount, called critical mass, is kept together. Soon...
