Element Rubidium

product line of name from the Latin word rubidius subject matter dark trigger-happydish or deepest carmine. nuclear military issue37 symbolismRb atomic Weight85. 4678 recite what? atomic number 37 is articulate asroo-BID-ee-em. uncoveringR. Bunsen, G. Kirchoff 1861 (Germany), discove vehement atomic number 37 in the mineral petalite via its dark red unearthly lines. grammatical constituent Classification groundwork Metal dumbness (g/cc)1. 532 Melting depict (K)312. 2 turn Point (K)961 expressionsoft, silvery-white, highly oxidizable metal atomic gas constant (pm)248 Atomic Volume (cc/mol)55. 9 Covalent universal gas constant (pm)216 Ionic Radius147 (+1e) Specific wake (20C J/g mol)0. 360 Fusion heat up (kJ/mol)2. 0 vapor Heat (kJ/mol)75. 8 Pauling Negativity fare0. 82 set-back Ionizing Energy (kJ/mol)402. 8 Oxidation States+1 radiator grille organiseBody-Centered Cubic Lattice Constant (A)5. 590 CAS register Number7440-17-7 Properties rubidium may be li quid at room temperature. It ignites ad lib in blood line and reacts violently in water, setting ardour to the liberated hydrogen. Thus, rubidium must be stored under run dry mineral oil, in a vacuum, or in an waterlogged atmosphere. It is a soft, silvery-white metal-looking element of the base of operations group. rubidium forms amalgams with mercury and alloys with gold, sodium, potassium, and cesium.atomic number 37 glows red-violet in a flame test. Rubidium Trivia Rubidium melts just a little above body temperature. Rubidium was discovered victimisation spectroscopy. When Bunsen and Kirchoff examined their render of petalite, they found 2 red spectral lines deep into the red part of the spectrum. They named their invigorated element rubidium after the Latin wordrubidus signification deepest red. Rubidium is the gage most confident(p) element. Rubidium lot be utilise to give fireworks a red-violet color. Rubidium is the twenty-thirdmost luxuriant element i n the Earths crust. Rubidium chloride is use in biochemistry as a biomarker to trace where potassium is taken up by living organisms. The hyper-fine electron structure of Rubidium-87 is employ in or so atomic quantify to maintain accuracy. The isotope Ru-87 was apply by Eric Cornell, Wolfgang Ketterle, and Carl Wiemen to put up a Bose-Einstein condensate. This earn them the 2001 Nobel Prize in Physics.
