Uses of Group 0 Elements
Helium
There are many uses for helium, it is commonly used in balloons, it is used in fiber optics for high-speed internet and in computer hard drives !
Neon
Neon is used in signs to make them look more attractive and cooler. It is used in lasers and is used by divers for respiration as it has less insolubility in our blood than nitrogen gas.
Argon
Argon lasers are used in the healthcare as it can target areas with extreme precision. It is used in wine barrels to displace air as it is denser than air it settles upon the wine protecting it from impurities. It is used to preserve old documents, it creates a protective atmosphere, protecting it from degradation and damage
Krypton
It is used in flash lamps for high-speed photography. It is used to make luminous signs for directing airplanes on the runway. It is used to create white light bulbs for cinematographic purposes.
Xenon
Used to detect radiation is various instruments. Xenon is used in medicine as a general anesthetic and in medical imaging. Modern ion thrusters for space travel use Xenon.
Radon
Used for cancer therapy. Radon is used to track air masses to a limited level. Changes in groundwater radon concentrations help in the prediction of Earthquake.
Properties
General Properties
-
- They are monatomic gases - they exist as individual atoms, such as He, Ar, etc.
-
- They are color less, odorless and tasteless gases at room temperature
-
Densities
The density of a substance is its mass per unit volume. For example, a small piece of a substance with a high mass has a high density.
The particles in gases are widely spaced, so the noble gases have low densities as they have low masses :
Helium, at the top of group 0, has
the lowest density in the group
-
Radon, at the end of group 0, has the highest density in the group

Importance of Group 0
Group 0 is arguably the most unique group in the periodic table: one of the only that doesn't react.
They have 2 or 8 valance electrons and hence fulfill the octet rule. This would mean that they are unlikely to react
Even though it is called group 0, the elements inside have a valance of 2 or 8

Electronic Configuration
The electronic Configuration for Group 0 is quite unique and interesting. Unlike other groups, the group number '0' does not tell the number of valance electrons each atom has.
