PHElement 10, Neon: a pure sample of the famous noble gas in a glass ampule encased within a lucite cube. But how can we know that the glass tube is actually filled with neon gas? If the sample is brought near the 50,000 Volt high frequency electric field of a miniature Tesla coil, the gas will glow with the characteristic orange light from the electron energy transitions specific only to neon. Note that the glow deceases as the sample is moved away from the coil in proportion to the electric field intensity- and that there is an excitation threshold, the gas needs a higher intensity (closer to coil) to initiate the glow discharge but will still glow when moved further away. ➡️ Follow the link in my profile for info on where to get this element cube and many other amazing items featured here on @physicsfun #physics #physicstoy #physicsfun #neon #hydrogen #nitrogen #helium #argon #krypton #xenon #gascollection #emissionspectra #excitation #spectra #breakdownvoltage #paschenslaw #glowdischarge #glowdischargetube #teslacoil #highvoltage #lightbulb #science #scienceisawesome
