Neon, chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colorless, odorless, tasteless, and lighter than air, neon gas occurs in minute quantities in Earth’s atmosphere and trapped within the rocks of Earth’s crust.
Its discovery was marked by the distinctive bright red emission spectrum it exhibited, leading to its immediate recognition as a new element. The name neon originates from the Greek word νέον, a neuter singular form of νέος (neos), meaning 'new'. Neon is a chemically inert gas, with no known uncharged neon
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.
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.
23 Αυγ 2018 · The most common use of the gas is in neon signs, which have a century-long history. First developed by French engineer Georges Claude in 1902, neon lights create light by applying...
