Whoever came up with this question didn't understand the material.
The answer is probably supposed to be "helium and neon."
Noble(nonreactive) gases like argon
All noble gases - He, Ne, Ar, Kr, Xe - were used in lasers.
Light bulbs are typically filled with argon, a noble gas. Argon is used because it is inert and helps prevent the filament from oxidizing and burning out quickly. In some cases, light bulbs may also contain a small amount of nitrogen or other gases to improve efficiency and longevity.
The gases used in many light bulbs, such as argon and krypton, are highly unreactive and belong to the noble gases group in the periodic table. This group is located in the far right column, specifically in Group 18. Noble gases are characterized by their full valence electron shells, which contribute to their chemical stability and low reactivity.
Yes, argon is a noble gas and is classified as a non-metal. It is colorless, odorless, and tasteless. Argon is commonly used in light bulbs, welding, and in certain types of lasers.
Using a higher quality filament made of tungsten can help light bulbs last longer. Additionally, running the light bulb at a lower wattage or voltage can also increase its lifespan.
No, hydrogen is not typically used to fill light bulbs. Light bulbs are usually filled with inert gases like nitrogen or argon to prevent oxidation of the filament, which would reduce the bulb's lifespan.
The noble gas used in light bulbs and photographs is argon. Argon is used in light bulbs to prevent filament degradation and in photographs to create a stable environment for preserving prints and negatives.
some noble gases is present inside it
The noble gas commonly used in light bulbs is argon. It helps prevent the filament from oxidizing and prolongs its life by providing an inert atmosphere. In photographic applications, krypton is often used in certain types of flash bulbs and photographic lighting, as it produces a bright light with a high color temperature. Both gases are effective due to their non-reactive properties.
Noble gases are primarily used in lighting, such as neon signs, as they are non-reactive and produce colorful light when electrified. They are also used in industries such as welding, electronics manufacturing, and refrigeration due to their stability and lack of chemical reactivity. Additionally, noble gases like helium are used in applications such as cooling superconducting magnets and inflating balloons.
Noble gases are a group of elements that are colorless, odorless, and have low reactivity. Helium is used in balloons and as a coolant in MRI machines. Neon is used in neon signs. Argon is used in welding and as a filler gas in light bulbs. Krypton is used in lighting and lasers. Xenon is used in lighting, anesthesia, and in plasma display panels. Radon is radioactive and used in cancer treatment.
