Ununennium Ununennium, also known as eka-francium or simply element 119, is the hypothetical chemical element with atomic number 119 and symbol Uue.Ununennium and Uue are the temporary systematic IUPAC name and symbol, until a permanent name is decided upon.In the periodic table of the elements, it is expected to be an s-block element, an alkali metal, and the first element in the eighth period.or example, ununennium is expected to be less reactive than caesium and francium and to be closer in behavior to potassium or rubidium, and while it should show the characteristic +1 oxidation state of the alkali metals, it is also predicted to show the +3 oxidation state unknown in any other alkali metal.

Palladium Palladium is a chemical element with symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by William Hyde Wollaston.alladium is one of the three most popular metals used to make white gold alloys (nickel and silver can also be used). Palladium-gold is a more expensive alloy than nickel-gold, but seldom causes allergic reactions (though certain cross-allergies with nickel may occur).

Period 3 element Silicon is a chemical element with symbol Si and atomic number 14. It is a tetravalent metalloid, more reactive than germanium, the metalloid directly below it in the table.Controversy about silicon's character dates to its discovery; it was first prepared and characterized in pure form in 1823.ilicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure free element in nature. It is most widely distributed in dusts, sands, planetoids, and planets as various forms of silicon dioxide (silica) or silicates.

Uranium Mining Overview The atomic number of uranium is 92, meaning that it has 92 protons and occupies place number 92 in the periodic table. It occurs naturally in six isotopes, U-233 to U-238 and therefore contains between 141 and 146 neutrons. The most common isotope is U-238 with a relative abundance of 99.3%.

Mercury (element) Mercury is a chemical element with symbol Hg and atomic number 80. It is commonly known as quicksilver and was formerly named hydrargyrum. A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. Mercury occurs in deposits throughout the world mostly as cinn

Explainer: What is polonium? What is polonium? Polonium is a rare and highly radioactive element. It is found naturally in the atmosphere and in the earth’s crust, though in miniscule quantities. Marie Curie discovered the element in the late 19th century and named it after her native country of Poland (in Latin: Polonia). It has dozens of isotopes.

- Praseodymium is a chemical element with symbol Pr and atomic number 59. Praseodymium is a soft, silvery, malleable and ductile metal in the lanthanide group.It is valued for its magnetic, electrical, chemical, and optical properties.It is too reactive to be found in native form, and when artificially prepared, it slowly develops a green oxide coating.n the 1930s it was found (Beck) that praseodymium dioxide could be precipitated from KOH/NaOH eutectic melts, by oxidation by electrochemistry, or by sodium chlorate. This formed the basis of a small-scale laboratory purification method. The relatively pure free metal itself was not prepared until 1931.

Plutonium 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 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.

- The isotope of element 118 with mass number 293 identified at Berkeley Lab contains 118 protons and 175 neutrons in its nucleus. By comparison, the heaviest element found in nature in sizeable quantities is uranium which, in its most common form, contains 92 protons and 146 neutrons.lthough both new elements almost instantly decay into other elements, the sequence of decay events is consistent with theories that have long predicted an island of stability for nuclei with approximately 114 protons and 184 neutrons.
