Plutonium

atomic sum up 94         Plutonium is a radioactive metallic element. Although it is now and then base in nature, mostly all of our atomic number 94 is produced by artificial means in a lab. The eat upicial chemical symbol for plutonium is Pu, overture from its first and third letters. Its atomic number is ninety-four. Plutonium is fitted to maintain its solid state until very high temperatures, firmness of purpose at six hundred and forty degrees Celsius, and boiling at three thousand four hundred and sixty degrees. The density 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 contributed to the stripping of thre e more radioactive elements, Einsteinium (Es), millivolt (Md), and atomic number 102 (No). Plutonium was Seaborgs first discovery. Its name came from Pluto, the major 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 dangerous and virulent element because it rapidly gives off radiation in the relieve oneself of alpha particles. Alpha particles, which are identical to the nucleus of a helium atom, consist of ! two protons and two neutrons tightly demarcation together. Although the particles can only propel about five centimeters in the air, they can cause ample damage when the enter the body, make cancer and other safe health problems. Beyond the danger of their radiation, Plutonium will impromptu explode when a accredited amount, called critical mass, is kept together. Soon...
