neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colourless, odourless, tasteless, and lighter than air, neon gas occurs in minute quantities in Earth’s atmosphere and trapped within the rocks of Earth’s crust.
Neon is the second-lightest noble gas, after helium. Like other noble gases, neon is colorless and odorless. It glows reddish-orange in a vacuum discharge tube. It has over 40 times the refrigerating capacity (per unit volume) of liquid helium and three times that of liquid hydrogen. [3]
8 Απρ 2023 · In several types of gas-filled electron tubes, Ne is used solo or in mixes with other gases. Because helium is less soluble in blood than nitrogen at high pressure, marine divers utilize a combination of helium and Ne for breathing.
Identification. Classification, Properties and Characteristics of Neon. Atomic Data of Neon (Element 10) How Commonly is Neon Used. Is the Element Toxic. Interesting Facts. What is Neon. Neon (NEE-on) is classified as a non-metal, represented by the chemical symbol Ne, belonging to the noble gas family.
Neon is a noble gas belonging to first p-block of periodic table. It is the first element forming a true octet of electrons and hence is inert just like its lighter analogue, helium. It is the second lightest noble gas and glows reddish-orange in vacuum discharge tube. Neon is a colourless, odourless monoatomic gas.
30 Απρ 2013 · Neon is the fifth most common element in the universe, and is formed by helium and oxygen nuclei fusing. It is found both in our atmosphere and in Jupiter's. On Earth it is found in tiny quantities in the air (18 ppm), sea water (0.2 ppm), and in the crust (70 ppt).
