No.
Neon is a gas. It does not contain anything as it is an element.
As all chemical elements the neon atom contain protons, neutrons and electrons.
No, not all neon signs actually contain neon gas. While neon signs were originally made with neon gas which produced a distinct red-orange color, other gases such as argon, helium, and mercury vapor are also commonly used in modern neon signs to produce different colors.
The element in gaseous or liquid neon is neon itself. Just the state of matter is different.
yes
It contains neon gas as it is also given in its name "neon light". However, it does contain other gases too but in negligible amounts.
Since gases occupy the same volume at STP regardless of their identity, a 5 L cylinder will contain the same number of gas particles for both nitrogen and neon. However, nitrogen is heavier than neon, so it will contain a greater mass of gas particles.
I guess the question is related to neon lamps rather than element neon. Neon lamps do use xenon gas it it. By varying the composition of gases used, the colour given out by the neon lamps can be changed.
No, neon is not a naturally occurring component of food. Neon is a colorless, odorless, and inert gas commonly used in neon signs and lighting but is not found in food products.
Neon is a gas so it actually can not be mined. It is actually obtained by fractional distillation of Air.
The gas used in fluorescent lamps is argon. Also are used sodium vapors lamps (yellow light). The incandescent lamps have 93 % argon and 7 % nitrogen. Neon is used for red lamps.
Air is called a mixture because air contain not only one element or one compound; air contain many elements and compounds: nitrogen, oxygen, argon, carbon dioxide, water vapours, helium, neon, krypton xenon, ozone, radon, pollutants. The composition of air was established by chemical analysis; from the second half of the XVIIth century gas after gas were discovered in air.
