Noble gases are a group of inert, non-reactive elements found in Group 18 of the periodic table, known for their full valence electron shells that make them extremely stable. They include helium, neon, argon, krypton, xenon, and radon, and have significant applications in lighting, welding, and as inert environments for chemical reactions.

Helium is a noble gas with the atomic number 2, known for its low density and inertness, making it invaluable in applications requiring non-reactive environments, such as in cryogenics and as a protective gas in welding. Its scarcity on Earth, primarily extracted from natural gas reserves, underscores its importance and the need for sustainable management of its resources.

Helium

Neon is a noble gas that is colorless, odorless, and inert under standard conditions, making it a key element in lighting and signage due to its ability to emit a distinct reddish-orange glow when electrically charged. Its rarity in the Earth's atmosphere and unique properties also make it valuable in scientific research and various industrial applications.

Neon

Argon is a noble gas, making it inert and non-reactive under most conditions, which is why it's widely used in applications requiring a stable atmosphere, such as in welding and as a protective layer in the production of titanium and other reactive elements. It is the third most abundant gas in the Earth's atmosphere, making it readily available for industrial and scientific use.

Argon

Krypton is a noble gas found in the Earth's atmosphere, known for its use in lighting and photography due to its bright white light when electrified. It is chemically inert, making it safe for various applications, but its rarity and extraction difficulty contribute to its high cost.

Krypton

Xenon is a noble gas that is colorless, dense, and odorless, known for its very low chemical reactivity due to its full valence shell of electrons. It is used in various applications, including in lighting, anesthesia, and as a propellant in ion thrusters for spacecraft.
