The lightest element is hydrogen, H2, which is also the most common. Hydrogen is very reactive and forms water when it interacts with oxygen.Know More
Hydrogen has the following properties:
Hydrogen is a colorless and odorless gas with the lowest density of all the gases. There is evidence suggesting that hydrogen could become a clean fuel source, and it is used to power some buses and cars. In the chemical industry it is used to produce ammonia as a fertilizer, and it removes sulfur during oil production. In addition, it hydrogenates oils to produce fats like margarine.
Other common uses for hydrogen include filling balloons and airships, as well as forming a protective environment during glass sheet manufacturing. As hydrogen reacts with oxygen to produce water, it can become problematic when used in airships and balloons.
In the human body hydrogen exists to form hydrogen bonds. However, it is not chemically active in other ways. As well as being common on Earth, hydrogen is found elsewhere in the solar system. For example, Jupiter is primarily made from hydrogen.Learn more about Atoms & Molecules
Francium has the lowest electronegativity of the elements listed on the Pauling Electronegativity Scale. The Angelo State University website defines electronegativity as an atom's ability to attract the shared electrons found in covalent bonds.Full Answer >

No element has the chemical symbol "Nu." Other symbols that may be mistaken for "Nu" include: "Na," "Ne," and "N." "Na" stands for sodium, while "Ne" stands for neon, and "N" stands for nitrogen. Another possible element that could be misread as "Nu" is "Au," which stands for gold.Full Answer >
The electron is the lightest particle of the atom. It has a mass of 9.1 x 10-28 grams. Comparing this mass to that of the proton's at 1.6726 x 10-24 grams, an electron is nearly 0.0005 times the proton's mass.Full Answer >
