It just is! Gosh..
A neon clock can be useful because it can also double up as a nightlight. They usually have quite a strong glow about them and so when it is otherwise dark they shed enough illumination for people to see.
Neon is chemically inert, meaning it is very unreactive. Its outer electron shell is full, so it is stable and does not readily form chemical bonds with other elements. This property makes neon useful for applications where a non-reactive atmosphere is needed, such as in neon signs.
Neon emits a bright red-orange light when an electric current is passed through it, making it ideal for use in neon signs and lighting. It is a noble gas, which makes it stable and non-reactive, allowing it to maintain its glow for a long time. Additionally, neon is abundant in the atmosphere, making it readily available for commercial use.
Jantecneon is a great website to buy custom neon signs. It gives you a large selection of the generic neon signs that are useful for many high street businesses, as well as accessories for your signs and finally some custom neons signs for those looking for something a little out of the ordinary.
Go to a parts house and purchase a Haynes manual. It will be very useful as it covers the majority of the car.
Neon has a low boiling point, around -246 degrees Celsius (-411 degrees Fahrenheit), which means it transitions from a gas to a liquid at very low temperatures. This property is due to neon's weak intermolecular forces, specifically van der Waals forces, resulting from its status as a noble gas with a complete electron shell. Consequently, neon remains in gaseous form at typical atmospheric conditions, making it useful in applications like neon signs and lighting where its gaseous state is advantageous.
Every element can produce an emission spectrum, if it is sufficiently heated. Of the 4 elements that you mention, neon is the most useful, in terms of its emission spectrum, and it is used in a certain type of lighting.
Neon in German is - Neon (!) Neon tube is Neonröhre
One use of noble gases is in lighting, such as neon lights. Because noble gases are unreactive, they can be used in these applications as they do not readily form compounds or react with other substances, allowing for a stable and long-lasting light source.
