Neon signs are red-orange

any other color may be called neon signs, but actually have another gas in them.

each noble gas produces a different color when electricity is sent through

they contain only one gas at a time

Other noble gases such as argon or helium are often mixed with neon in neon signs to produce different colors and brightness levels. Each noble gas emits a unique color when an electric current passes through it, allowing for a variety of hues to be created in a neon sign. Additionally, mixing gases like argon can help enhance the overall brightness and longevity of the sign.

Because they light up when a current is passed through.

What groups of elements does the p block contain?

The p-block contains halogens and noble gases.


What are two noble gases?

Two noble gases are helium and neon. These gases are odorless, colorless, and generally do not react with other elements due to their fully-filled outer electron shells. They can be found in small quantities in the Earth's atmosphere.


Which region contain stable noble inert gases in other words which elements do not react with other element?

The noble inert gases, also known as noble gases, are found in Group 18 of the periodic table. These elements include helium, neon, argon, krypton, xenon, and radon. They are stable because their outer electron shells are fully filled, making them unlikely to react with other elements.


What are the other noble gases?

helium, neon, argon, krypton, xenon and radon are the 6 noble gases


Why cant noble gases mix with other elements?

!. Noble gases can be mixed with other gases. 2. Noble gases are unreactive (only a limited number of compounds are known today) because the valence electron shell is completely filled.


What distinguishes noble gases from other nonmetals?

Unlikely other elements in the periodic table, noble gases rarely form compounds with other elements.


Where do the noble gases get their name?

These gases generally dont react with any other elements and hence are considered 'noble'.


What are the other noble gases that are like helium?

HELIUM,NEON,ARGON,KRYPTON,XENON and RADON are the noble gases


What are gases that do not form compounds with other elements called?

Why are noble gases infinitely soluble in other noble gases?

Noble gases are infinitely soluble in other noble gases because they are non-reactive and have very weak intermolecular forces. This allows the noble gas atoms to mix together easily and uniformly, creating a homogeneous solution without any chemical reactions occurring.


What are characterisatics of noble gases?

Noble gases have completely filled valence orbitals. Helium has 2 valence electrons, whereas other noble gases have 8. They are generally chemically inert at STP.


How are the noble gases different from all the other gases in the periodic table?

Noble gases have completely filled orbitals and are stable and chemically inert (non-reactive).
