A macroscopic sample of rubidium refers to a quantity of rubidium that is large enough to be observed and measured without the need for specialized equipment, typically weighing several grams or more. Rubidium is a soft, silvery-white alkali metal that is highly reactive and can be found in nature in trace amounts in minerals like lepidolite. In its pure form, rubidium can be obtained through the reduction of rubidium chloride with metallic potassium. Due to its reactivity, a macroscopic sample must be stored under oil or in an inert atmosphere to prevent oxidation.
Rubidium has two natural isotopes (85Rb and 87Rb) and 30 artificial isotopes.
The atomic number of rubidium is 37.
The atomic mass of rubidium (Rb) is approximately 85.4678 atomic mass units.
The name for RbHCO3 is rubidium bicarbonate. It is a chemical compound composed of rubidium, hydrogen, carbon, and oxygen ions.
If consumed rubidium may be poisonous, but other wise it isn't.
The chemical symbol of zinc is Zn; "macroscopic sample element" is a strange formulation in chemistry.
because
A macroscopic sample of neon would simply refer to a visible quantity of neon gas. This could be in the form of a container filled with neon gas or a neon sign, where neon gas is used as the filling. Neon is a colorless, odorless, inert gas that emits a distinct reddish-orange glow when used in these applications.
The half life of rubidium-87 is 4,923(22) ex.10 years.
Rubidium was discovered in 1861 by German chemists Robert Bunsen and Gustav Kirchhoff through a spectroscopic analysis of mineral samples. They identified a characteristic red line in the sample's spectrum, which led to the discovery of the element rubidium.
What does macroscopic mean
Rubidium hypochlorite is the name for this chemical formula.
The word equation for rubidium and chlorine is: rubidium + chlorine -> rubidium chloride.
Rb is the symbol for the element, rubidium.
examples of macroscopic system
No such chemical as 'Rb O'. The nearest is Rb2O , which is Rubidium oxide.
A macroscopic cell can be seen without the aid of a microscope.
