Do all of the noble gases have at least 3 electron shielding layers?
No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.
Is it true that all noble gases have at least three shielding layers?
No. Not sure what you mean by a shielding layer- I would take this as the filled electron shells below the "outer", highest energy layer-- He has none, Neon has one , Argon has two.
What are the common gases used in GMAW Process?
Carbon dioxide, Argon, Helium, but not Nitrogen, can be used as 'shielding' gas in Gas Metal Arc Welding.
What is debye shielding?
de3bye shielding with figure
What are the principle of radiation safety?
This depends upon if you mean protection from general radiation or once you've already been exposed. There are several foods and supplements you can take to protect from the effects. Children know Nuclear Weapons are Very Bad; it is too bad they do not understand the Vagaries of Power. It is Good that they Will.

Is O2 also added to shielding gas in tungsten arc welding process?
No, that would defeat the purpose. Shielding gases must be inert (e.g. argon, helium).
What prevents contamination of the weld puddle shielding gases are used to displace from the weld zone?
Dross
Why CO2 can not be used as shielding gas in GTAW?
CO2 is an oxygen compound or a non-inert gas,the purpose of a shielding gas is to shield the weld and the electrode from oxygen. argon, nitrogen and helium are the most common gases used for GTAW

How may bremsstrahlung production be minimized?
by using shielding material with low Z..

The cause of air pollution?
There are many gases. Major reason is industrial gases.
What is an example of active gas?
These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or activeshield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals.
The noble gases are almost completely nonreactive for this reason they are sometimes called?
Inert Gases
Why there were no gases in Mercury?
the reason there are no gases in mercury the molecules moves fast at high temperature
The greatest cause of air pollution?
There are many gases. Major reason is industrial gases.
