A radioactive actinide metal, neptunium is the first transuranic element.Its position in the periodic table just after uranium, named after the planet Uranus, led to it being named after Neptune, the next planet beyond Uranus.A neptunium atom has 93 protons and 93 electrons, of which seven are valence electrons. The list applies to chemicals of the same structural formula (including hydrates) regardless of name or CAS number. The actinide (/ k t n a d /) or actinoid (/ k t n d /) series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.The actinide series derives its name from the first element in the series, actinium. Indium - Element information, properties and uses | Periodic Table When bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and mercury in the solid state.

In its pure form, molybdenum is a silvery-grey metal with a Mohs hardness of 5.5 and a standard atomic weight of 95.95 g/mol. The ferric ions of the Prussian blue are reduced to ferrous ions by activation of the photocatalyst particles. A method of removing radioactive cesium using the radioactive cesium adsorbent includes preparing a composition comprising photocatalyst particles and Prussian blue; preparing a precursor It is nonmetallic and tetravalentits atom making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Barium borate, BaB 2 O 4 (BBO) Most common allotrope. Refractive index of MgF2 (Magnesium fluoride) - Dodge-o Hafnium(IV) oxide is the inorganic compound with the formula HfO 2.Also known as hafnium dioxide or hafnia, this colourless solid is one of the most common and stable compounds of hafnium.It is an electrical insulator with a band gap of 5.3~5.7 eV. Uranium dioxide It has also been used to coat ball bearings in Formula 1 racing cars because of its low friction. Explain why the symbol for an atom of the element oxygen and the formula for a molecule of oxygen differ. Dispersion formula $$n^2-1=\frac{3.0249^2}{^2-0.1353406^2}+\frac{40314^2}{^2-1239.842^2}$$ Comments. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. At this point, it is the only superhard material with metallic behavior. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier homologues strontium and barium.It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron Hafnium(IV) oxide Note: There are elements for which spellings may differ, such as aluminum/aluminium, sulfur/sulphur, and caesium/cesium.

Titanium carbide, Ti C, is an extremely hard (Mohs 99.5) refractory ceramic material, similar to tungsten carbide.It has the appearance of black powder with the sodium chloride (face-centered cubic) crystal structure.. CAS numbers by chemical compound Neptunium is a chemical element with the symbol Np and atomic number 93. Refractive index of BaB2O4 (Barium borate, BBO) - Eimerl-o It has a melting point of 2,623 C (4,753 F); of the naturally occurring elements, only tantalum, osmium, rhenium, tungsten, and carbon have higher melting points. 1. Carbon makes up only about 0.025 percent of Earth's crust. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.At standard temperature and pressure, two atoms of the element bind to form N 2, Carbon Phosphorus - Periodic Table Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2 ions held together by ionic bonding.
