Chromate IonRubidium Chromate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Rubidium (Rb) atomic and molecular weight, atomic number and elemental symbol Rubidium (atomic symbol: Rb, atomic number: 37) is a Block S, Group 1, Period 5 element with an atomic weight of 5.4678. Rubidium Bohr ModelThe number of electrons in each of Rubidium's shells is [2, 8, 18, 8, 1] and its electron configuration is [Kr] 5s1. The rubidium atom has a radius of 248 pm and a Van der Waals radius of 303 pm. Rubidium is highly reactive, with properties similar to other Group 1 akali metals, e.g., rapid oxidation in air. In its elemental form, rubidium has a gray white appearance. Rubidium is found in the minerals lepidolite, leucite, pollucite, carnallite, and zinnwaldite as well as some potassium minerals. Rubidium was discovered by Robert Bunsen and Gustav Kirchhoff in 1861 and was first isolated by George de Hevesy. The name Rubidium, originates from the Latin word rubidus, meaning "dark or deepest red."

Chromium (Cr) atomic and molecular weight, atomic number and elemental symbolChromium (atomic symbol: Cr, atomic number: 24) is a Block D, Group 6, Period 4 element with an atomic weight of 51.9961. Chromium Bohr ModelThe number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration is [Ar] 3d5 4s1. Chromium was first discovered by Louis Nicolas Vauquelin in 1797. It was first isolated in 1798, also by Louis Nicolas Vauquelin. The chromium atom has a radius of 128 pm and a Van der Waals radius of 189 pm. In its elemental form, chromium has a lustrous steel-gray appearance. Elemental ChromiumChromium is the hardest metal element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it tranforms into a paramagnetic solid. The most common source of chromium is chromite ore (FeCr2O4). Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color.
