titanium oxidation states

By mass, aluminium makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below.Silicon is a hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor.As an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free element on Earth.

Arsenic is a metalloid.Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. Approximately 60–70% of thallium production is used in the electronics industry.Lead is a heavy metal that is denser than most common materials. Although neodymium is classed as a rare earth, it is a fairly common element.Promethium is one of only two such elements that are followed in the periodic table by elements with stable forms. Chemically, indium is similar to gallium and thallium.Tin is a post-transition metal in group 14 of the periodic table. and Gay-Lussac, L.-J.Discoverer: Priestley, Joseph and Scheele, Carl WilhelmDiscoverer: Ramsay, Sir William and Strutt, John (Lord Rayleigh)Discoverer: Del Rio, Andrés Manuel (1801) and Sefström, Nils Gabriel (1830)Discoverer: Ramsay, Sir William and Travers, MorrisDiscoverer: Bunsen, Robert Wilhelm and Kirchhoff, Gustav RobertDiscoverer: Reich, Ferdinand and Richter, HieronymusDiscoverer: Ramsay, William and Travers, Morris WilliamLanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite.Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. It exists in three phases, rutile, which is the most stable one, anatase, and brookite.

The bulk properties of astatine are not known with any certainty.Radon is a radioactive, colorless, odorless, tasteless noble gas.

Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten.Neptunium metal is silvery and tarnishes when exposed to air. Cerium is the second element in the lanthanide series. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel.Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.Iron is a metal in the first transition series. A freshly exposed surface of pure copper has a reddish-orange color.

Under standard conditions, it is the lightest metal and the lightest solid element.

In fact their absorption cross-sections are the highest among all stable isotopes.Terbium is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. An atom of an element in a compound will have a positive oxidation state if it has had electrons removed. The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.Cadmium is a soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Its boiling point is the lowest among all the elements.It is a soft, silvery-white alkali metal. The oxidation state of a molecule or compound shows the overall charge of the species being observed. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine.Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv). Its properties are thus intermediate between those of chlorine and iodine.Krypton is a member of group 18 (noble gases) elements. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide.

The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium).Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.Tungsten is a rare metal found naturally on Earth almost exclusively in chemical compounds.

All of its isotopes are radioactive.

Holmium is a relatively soft and malleable silvery-white metal.Erbium is a silvery-white solid metal when artificially isolated, natural erbium is always found in chemical combination with other elements. A Varian V-550 turbo- temperature and pressure conditions [31].

All isotopes of radium are highly radioactive, with the most stable isotope being radium-226.Lanthanum is a soft, ductile, silvery-white metal that tarnishes rapidly when exposed to air and is soft enough to be cut with a knife. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths.Actinium is a soft, silvery-white radioactive metal. It is one of the least reactive chemical elements and is solid under standard conditions. 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.Potassium was first isolated from potash, the ashes of plants, from which its name derives.
