When it comes to the periodic table, there are a group of elements known as rare gases or noble gases. These gases are unique because they have low chemical reactivity due to their full valence electron shells. Rare gases are found in Group 18 of the periodic table and include elements such as helium, neon, argon, krypton, xenon, and radon.
Properties of Rare Gas
Rare gases are colorless, odorless, tasteless, and non-flammable. They are known for their low boiling and melting points, as well as their low densities. These gases are used in various industries and applications due to their inert nature.
Uses of Rare Gas
One of the most common uses of rare gas is in lighting. Neon lights, for example, use neon gas to produce a bright red-orange glow. Argon is often used in light bulbs to prevent the filament from oxidizing. Helium is used in balloons, airships, and even MRI machines.
Occurrence of Rare Gas
Rare gases are found in small quantities in the Earth's atmosphere. They are produced during the radioactive decay of elements such as uranium and thorium. These gases can also be found in some minerals and natural gas deposits.
Helium is the second most abundant element in the universe, but it is rare on Earth. Xenon is used in flash lamps and high-intensity arc lights due to its bright light output. These rare gases play a crucial role in various scientific, industrial, and commercial applications.
