Neon is a colorless, odorless, inert monatomic gas under standard conditions, with approximately two-thirds the density of air. Neon was discovered in 1898 alongside krypton and xenon, identified as one of the three remaining rare inert elements in dry air after the removal of nitrogen, oxygen, argon, and carbon dioxide.
Because its boiling point is −246 °C (−411 °F), neon remains, along with helium and hydrogen, in the small fraction of air that resists liquefaction upon cooling to −195.8 °C (−320.4 °F, the boiling point of liquid nitrogen).
SOLID: normal density: 1444 kg/cu m (triple point); Heat of vaporization: 2.139 kJ/mol (triple point); Heat of fusion: 0.335 kJ/mol (triple point)
Neon is a colourless, odourless gas that has a melting point of −248.59°C and a boiling point of −246.046°C. It is mainly used for neon signs and as a cryogenic refrigerant.
The cosmogenic component is mainly detected in 21 Ne and can be used to determine cosmic-ray exposure ages of rock samples, including meteorites exposed during travel through space and boulders exposed by melting of glacial ice (Fig. IUPAC.10.1).
9 kwi 2020 · It reaches its boiling point at −246.046°C, −410.883°F, 27.104 K, while the melting point is achieved at −248.59°C, −415.46°F, 24.56 K. This rare monoatomic atmospheric gas has an unknown electronegativity according to Pauling, while the atomic radius of neon according to van der Waals is 0.16 nm.
30 gru 2019 · Neon has a Melting Point of -248.67°C, meaning at -248.67°C it will turn to a liquid. What is the Boiling Point for Neon? Neon has a Boiling Point of -246.048°C, meaning at -246.048°C it will turn to a Gas.
