This is a list of prices of chemical elements.Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.
These tables list values of molar ionization energies, measured in kJ⋅mol −1. This is the energy per mole necessary to remove electrons from gaseous atoms or atomic ions. The first molar ionization energy applies to the neutral atoms.
Rubidium sesquioxide is a chemical compound with the formula Rb 2 O 3 or more accurately Rb 4 O 6. In terms of oxidation states , Rubidium in this compound has a nominal charge of +1, and the oxygen is a mixed peroxide ( O 2− 2 ) and superoxide ( O − 2 ) for a structural formula of (Rb + ) 4 (O − 2 ) 2 (O 2− 2 ) .

The magnesium compound magnesium sulfate was first discovered in 1618 by a farmer at Epsom in England. Strontium carbonate was discovered in minerals in the Scottish village of Strontian in 1790. The last element is the least abundant: radioactive radium , which was extracted from uraninite in 1898.
Magnesium is absorbed orally at about 30% bioavailability from any water soluble salt, such as magnesium chloride or magnesium citrate. The citrate is the least expensive soluble (high bioavailability) oral magnesium salt available in supplements, with 100 mg and 200 mg magnesium typically contained per capsule, tablet or 50 mg/mL in solution.

In addition to the neutral rubidium oxalate Rb 2 C 2 O 4, there is also an acidic salt, rubidium hydrogen oxalate with the formula RbHC 2 O 4, which is isomorphic to potassium hydrogen oxalate KHC 2 O 4 [10] and forms monoclinic crystals, [11] and an acidic dioxalate with the formula RbHC 2 O 4 ·H 2 C 2 O 4, which exists as a dihydrate, has a ...
Rubidium azide has a high pressure structure transition, which occurs at about 4.8 kilobars of pressure at 0 °C. The transition boundary of the II/III transition can be defined by the relationship P = 4.82 + 0.0240 t {\displaystyle P=4.82+0.0240\,t} , where P {\displaystyle P} is the pressure in kilobars and t {\displaystyle t} is the ...
