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.
What else can I help you with?
How many years would it take half of the rubidium atoms in a piece of a rock to change into strontium?
The time it takes for half of the rubidium atoms in a sample to change into strontium is determined by the half-life of rubidium-87, which is approximately 48.8 billion years. This means that it would take about 48.8 billion years for half of the rubidium-87 atoms to decay into strontium-87.

What is macroscopic sample of neon?
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.
How long would it take for 1 2 sample of rubidium 87 to change into strontium 87?

How Rubidium was discovered?
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.
