Full Answer

Rubidium can be found on the periodic table under its atomic number 37 and its atomic weight of 85.4678. Rubidium is part of the alkali metals group on the periodic table. It can be a liquid at some temperatures, but at minus 100 degrees Celsius, it ignites in the air and reacts with water and ice. Rubidium forms alloys with cesium, sodium, gold and potassium and has a yellow, violet flame.

    Where does hydrogen come from?

    A:

    Hydrogen does not exist in pure form in nature and instead is produced from a primary energy source, such as fossil fuels, solar, geothermal and wind energy, or extracted from other elements such as oxygen. Hydrogen is found embedded in, or coexisting with, other elements on Earth, in water and in the atmosphere. Hydrogen is quite abundant but is often difficult to extract and separate from surrounding minerals and elements.

    What are some examples of elements?

    A:

    Hydrogen and ununoctium are two examples of the more than 100 elements that have either been discovered in nature or synthesized by scientists. All of the elements are arranged in the periodic table, which organizes the elements based on atomic mass, number of valence electrons, and physical and chemical characteristics.

    Is flourine a metal?

    A:

    Fluorine is a non-metal, highly reactive element that does not occur naturally in nature. It is instead created through the electrolysis of hydrofluoric acid and potassium fluoride. It is also produced through the electrolysis of molten potassium acid fluoride (KHF2).

    What did Aristotle contribute to the understanding of atoms?

    A:

    Aristotle's contribution to the understanding of atoms was to help dispel the commonly held belief of his time that the indivisible building blocks of matter were uniform in nature and had no unique or characteristic properties. He argued that the atoms of a specific substance must instead maintain the unique properties of that substance rather than all atoms remaining similar in nature. Aristotle also noted that some substances appeared to be pure and that others were formed from the combinations of these pure substances, an observation which led to the understanding that elements could be combined to form compounds with new and unique properties.
