Plutonium (94 Pu) is an artificial element, except for trace quantities resulting from neutron capture by uranium, and thus a standard atomic weight cannot be given. Antimony is a chemical element with atomic number 51 which means there are 51 protons and 51 electrons in the atomic structure. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Other members of the element group stick to magnets, but plutonium can have a variable number of electrons in its valence shell, which makes it difficult for the unpaired electrons to align in a magnetic field. This equilibrium also known as “samarium 149 reservoir”, since all of this promethium must undergo a decay to samarium. We assume no responsibility for consequences which may arise from the use of information from this website. The chemical symbol for Thallium is Tl. Neptunium - Electron Configuration and Oxidation States - Np, Uranium - Electron Configuration and Oxidation States - U, Protactinium - Electron Configuration and Oxidation States - Pa, Neptunium – Electron Configuration and Oxidation States – Np, Americium – Electron Configuration and Oxidation States – Am. Diagram of the nuclear composition, electron configuration, chemical data, and valence (outer electron) orbitals of an atom of plutonium-244 (atomic number: 94), the most stable isotope of this element. Since the mass of the electrons can be neglected, the total mass of neutrons and protons is the same as the mass of the atom. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. In nuclear industry, especially natural and artificial samarium 149 has an important impact on the operation of a nuclear reactor. Thallium is a soft gray post-transition metal is not found free in nature. Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas. It doesn't always act as expected. Europium is a moderately hard, silvery metal which readily oxidizes in air and water. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC. Element Name: Plutonium. Therefore are generally, for plutonium in periodic table of the closer. The chemical symbol for Nobelium is No. Conveniently for us, we have defined the mass of one neutron or proton to be equal to one atomic mass unit. Niobium is a soft, grey, ductile transition metal, often found in the minerals pyrochlore (the main commercial source for niobium) and columbite. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. Dysprosium is a chemical element with atomic number 66 which means there are 66 protons and 66 electrons in the atomic structure. New research shows that plutonium does not share electrons when it bonds with fluoride atoms. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. Therefore you can directly look for atomic number 94 to find Plutonium on periodic table. Electronic configuration: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 4d 10 5s 2 5p 6 4f 14 5d 10 6s 2 6p 6 5f 6 6d 0 7s 2 >> Back to key information about the element Mercury is a chemical element with atomic number 80 which means there are 80 protons and 80 electrons in the atomic structure. Atomic structure of Plutonium includes atomic number, atomic weight, electron configuration Isotopes of the same element have the same number of protons in their nuclei but differ by the number of neutrons. Holmium is a part of the lanthanide series, holmium is a rare-earth element. Its properties are thus intermediate between those of chlorine and iodine. The chemical symbol for Lead is Pb. Printed from, Molar Mass Calculations and Javascript Calculator, Nitrogen Dioxide, Ozone & Lead Partner to Increase Pollution Dangers to Urban Children, Plastics - From Recycling Bin to New Product, ADA Recommendation for Fluoride in Infant Diets, Asbestos, a Brief History its Uses & Health Risks, Asbestos, its Chemical & Physical Properties, Asbestos: A Manufacturing Health Hazard Dating to Prehistoric Times. The atomic number of each element increases by one, reading from left to right. Calculating the number of amu in one gram leads us to Avogadro’s number, roughly 6.022 x10^23. PLEASE, if you like an article we published simply link to it on our website do not republish it. The chemical symbol for Plutonium is Pu . Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. Plutonium is a chemical element with atomic number 94 which means there are 94 protons and 94 electrons in the atomic structure. Chemical Properties of Plutonium. Plutonium-235. Common chemical compounds are also provided for many elements. Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases. We use cookies to ensure that we give you the best experience on our website. The chemical symbol for Tin is Sn. Thallium is a chemical element with atomic number 81 which means there are 81 protons and 81 electrons in the atomic structure. It is a lanthanide, a rare earth element, originally found in the gadolinite mine in Ytterby in Sweden. Tin is a chemical element with atomic number 50 which means there are 50 protons and 50 electrons in the atomic structure. Isotopes of the same element have the same number of protons in their nuclei but differ by the number of neutrons. Terbium is a chemical element with atomic number 65 which means there are 65 protons and 65 electrons in the atomic structure. Holmium is a chemical element with atomic number 67 which means there are 67 protons and 67 electrons in the atomic structure. Its longest lived isotopes are 244 Pu, with a half-life of 80.8 million years, 242 Pu with a half-life of 373,300 years and 239 Pu with a half-life of 24,110 years. Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Plutonium is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. Caesium is a soft, silvery-gold alkali metal with a melting point of 28.5 °C, which makes it one of only five elemental metals that are liquid at or near room temperature. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233. Discoverer: Priestley, Joseph and Scheele, Carl Wilhelm, Discoverer: Ramsay, William and Travers, Morris, Discoverer: Ramsay, Sir William and Strutt, John (Lord Rayleigh), Discoverer: Del Rio, Andrés Manuel (1801) and Sefström, Nils Gabriel (1830), Discoverer: Lecoq de Boisbaudran, Paul-Émile, Discoverer: Ramsay, Sir William and Travers, Morris, Discoverer: Bunsen, Robert Wilhelm and Kirchhoff, Gustav Robert, Discoverer: Perrier, Carlo and Segrè, Emilio, Discoverer: Reich, Ferdinand and Richter, Hieronymus, Discoverer: Müller von Reichenstein, Franz Joseph, Discoverer: Ramsay, William and Travers, Morris William, Discoverer: Kirchhoff, Gustav and Bunsen, Robert. Anion is for plutonium table of neutral atom to the electrons. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. Other articles where Plutonium-239 is discussed: atomic bomb: The properties and effects of atomic bombs: of the isotopes uranium-235 or plutonium-239, it causes that nucleus to split into two fragments, each of which is a nucleus with about half the protons and neutrons of the original nucleus. Oxidation states are typically represented by integers which may be positive, zero, or negative. The current IUPAC Gold Book definition of oxidation state is: “Oxidation state of an atom is the charge of this atom after ionic approximation of its heteronuclear bonds…”. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine.
