The Unique Properties and Uses of Noble Gases
TLDR Noble gases, located on the far right side of the periodic table, are known for their inertness and unique properties. Despite being rare on Earth, helium is the second most abundant element in the universe and has various industrial applications. Other noble gases like neon, argon, krypton, and xenon also have specific uses, while radon poses a serious health threat.
Timestamped Summary
00:00
The noble gases are a group of elements located on the far right side of the periodic table, known for their inertness and unique properties.
01:57
Noble gases have a full set of electrons in their valence shell, making them inert and difficult to bind with other elements, resulting in their colorless, odorless, and monoatomic nature, and helium, the lightest noble gas, is the second most abundant element in the universe and is mostly obtained through radioactive decay.
03:42
In 1903, drillers in Kansas accidentally discovered the first helium on Earth, which is rare on our planet despite being one of the most common elements in the universe, and helium has various industrial applications including lifting balloons, welding, creating crystals, cooling MRI machines, and potentially being used for nuclear fusion.
05:27
Neon is the fifth most common component of atmospheric air, primarily used for neon lights, while argon is the third most common element in air and is cheaper than neon or helium.
07:12
Argon is commonly used in high-tech applications, welding, aerosol cans, and as a preservative, while krypton is more expensive and has fewer uses, and xenon is produced in supernovas and can be a problem in nuclear reactors.
08:55
Radon, the heaviest noble gas, is radioactive, expensive, and poses a serious health threat as it can accumulate in low-lying places and is the second-largest cause of lung cancer after smoking.
10:41
The noble gases, including the theoretical element Oganison, don't react with anything and have limited uses, but we unknowingly breathe them our entire lives.
