Neon: A pure sample of the famous noble gas in a glass ampule | Interesting Chemistry
Neon: A pure sample of the famous noble gas in a glass ampule encased in a lucite cube. But how can we know that the glass tube is actually filled with neon gas? If the sample is placed in a high-frequency electric field of 50,000 volts from a miniature Tesla coil, the gas will glow with a characteristic orange light from electron energy transitions that are unique to neon.
