The chemical element neon is the second lightest noble gas after helium. It is a colorless, odorless, and nonflammable element that is relatively nonreactive.
Neon is used for illuminating signs and as a coolant. It is also used in displays and high voltage indicators. However, the chemical element is very rare, and so obtaining it is a difficult task.
To get the element in its pure form, researchers must first turn it into a liquid at a very low temperature. This is done by fractional distillation.
The temperature range of liquid neon is the narrowest of any element. Liquid neon has a liquid temperature of -411 F.
Although neon is relatively inert, it can be hazardous if it is over-saturated. When it becomes too dense, it can become an asphyxiant.
Neo is the fifth most abundant element in the universe. Small quantities of the element are found in Earth’s crust and atmosphere.
Some people have reported that neon has the ability to form a compound with fluorine. However, this is not certain. Optical spectrometry research suggests that neon and fluorine could interact in nature.
It is rare for neon to exist in pure form on Earth. Most of the Earth’s neon is bound up in the Earth’s atmosphere.
The atomic number for neon is 10. While it is considered to be a noble gas, it does not easily form compounds in the presence of other elements.
The Allen electronegativity scale ranks neon as the most electronegative element. The scale uses atomic energy and chemical bond energies to determine the electronegativity of an element.
