Halides:- Silicon compounds, mostly carbides form silicon tet halides when they react with stable halogens. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. The chemical symbol for Thallium is Tl. Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation. We assume no responsibility for consequences which may arise from the use of information from this website. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Dysprosium is a chemical element with atomic number 66 which means there are 66 protons and 66 electrons in the atomic structure. The chemical symbol for Niobium is Nb. The chemical symbol for Dysprosium is Dy. These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). The unit of measure for mass is the atomic mass unit (amu). Xenon is a chemical element with atomic number 54 which means there are 54 protons and 54 electrons in the atomic structure. About 97% of Earth's crust is made of rocks and comprises silicon and oxygen compounds. Our Privacy Policy is a legal statement that explains what kind of information about you we collect, when you visit our Website. Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. Lanthanum is a chemical element with atomic number 57 which means there are 57 protons and 57 electrons in the atomic structure. Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. The chemical symbol for Ruthenium is Ru. The atomic number of silicon is 14 and its relative atomic mass is 28.085 u. The Standard English unit is pounds mass per cubic foot (lbm/ft3). Nearly all technetium is produced synthetically, and only minute amounts are found in the Earth’s crust. One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. Silicon is very reactive at higher temperatures. Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. The chemical symbol for Silver is Ag. Sodium is a soft, silvery-white, highly reactive metal. Titanium is a lustrous transition metal with a silver color, low density, and high strength. Chemically, indium is similar to gallium and thallium. Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. The chemical symbol for Praseodymium is Pr. After 32Si, 31Si has the second longest half-life at 157.3 minutes. Al2 (SO4) 3 + 3 Ca (OH) 2 → 3_CaSO4 + ? The chemical symbol for Titanium is Ti. Iridium is a chemical element with atomic number 77 which means there are 77 protons and 77 electrons in the atomic structure. Silicon compounds, mostly carbides form silicon tet halides when they react with stable halogens. Natural Silicon includes these three isotopes in 92.2% of silicon-28,  4.7% of  silicon-29, and 3.1% of silicon-30 respectively and all these isotopes are stable. It is relatively unreactive. Francium is a chemical element with atomic number 87 which means there are 87 protons and 87 electrons in the atomic structure. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Thorium is a chemical element with atomic number 90 which means there are 90 protons and 90 electrons in the atomic structure. Discoverer: Davy, Sir H. and Thénard, L.-J.
