About Rubidium Chromate

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.

See more Rubidium products. Rubidium (atomic symbol: Rb, atomic number: 37) is a Block S, Group 1, Period 5 element with an atomic weight of 5.4678. The 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 Bohr ModelRubidium is highly reactive, with properties similar to other Group 1 alkali 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 Bohr ModelThe number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron configuration is [Ar] 3d5 4s1. Louis Nicolas Vauquelin first discovered chromium in 1797 and first isolated it the following year. 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 metallic element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it transforms 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.
