Noble gases are located in Group 0 of the periodic table. They have special features that make them very useful in lighting, especially in neon signs.

One important thing about noble gases is that they have a full outer layer of electrons. This makes them very stable and non-reactive, meaning they don’t easily change or react with other substances. Because they are so stable, we can use them safely in different lighting applications.

Neon Signs

Neon signs are one of the best-known ways we use noble gases in lighting. These signs contain neon gas. When electricity flows through neon gas, it lights up in a bright reddish-orange color. Here’s how it works:

1. Electric Current: When electricity is applied, it gets the neon atoms moving.
2. Excited State: The atoms get energized, which means their electrons jump to a higher energy level.
3. Light Emission: As the excited electrons calm down and return to their normal level, they release energy as light.

Other Noble Gases

Besides neon, there are other noble gases that are also used in lighting:

• Argon: This gas is found in fluorescent lights and creates a blue light when electricity is added.
• Krypton and Xenon: These gases are used in some special lights called high-intensity discharge (HID) lamps. They produce a bright white light.

In short, noble gases are very stable and can produce bright colors when electricity is used. This makes them very important for modern lighting. They don’t just stay the same; they also shine brightly!
