Zodarion rubidum was created in 1914.
Not sure about rubidum, but rubidium is a metal.

The term half life describes the time taken for half of a total amount of radioactive isotopes to decay. However that doesn't mean that they all take exactly that length of time. Some will decay much more quickly than that and some more slowly. As such even though the half life is longer than the age of the earth, some of the Rubidum 87 isotopes will have decayed. Based on the proportion of rubidum 87 to the daughter isotopes you can still use this for dating materials younger than the half life of rubidum 87.
The chemical formula for rubidium acetate is RbC2H3O2.
This alkali metal is Rubidium Rb, having atomic no 37
It's a silver-gray metal with a mushy consistency, but you won't ever see any. It's not terribly common, plus it's so reactive that it never exists in nature by itself, only in a compound.
Strontium usually produces a ruby-colored flame test. When strontium is heated, it emits a bright red flame due to the energy absorbed by the electrons and then released as light in the red part of the spectrum.
The element that is used in Cesium. Usually it will come in the form of Cesium 133 because this is the most easily used form.
It's just Rubidium Sulfate. The name rubidium sulfate (sulfate is SO3)assumes that people can figure out the chemical formula based on the oxidation numbers of rubidium (+1) and sulfate (-2) and crisscrossing to get a net oxidation number of zero.
Yes, rubidium carbonate (Rb2CO3) contains ionic bonds. In this compound, the rubidium cation (Rb+) and carbonate anion (CO3^2-) are held together by strong electrostatic forces of attraction between their opposite charges, forming an ionic bond.
Rubidium+Phosporous+Chloride=Rubidum Phophide.
Most likely, the element is either sodium or mercury. Sodium is a soft, silver-colored metal that is quite reactive and commonly found in everyday items like table salt. Mercury is also silver in color and is the only metal that is liquid at room temperature.
