Why is argon purple?
The argon atom has 18 electrons and 18 protons. Its outer shell is full with eight electrons. Under standard conditions argon is an odorless and colorless gas. When argon is excited by a high voltage electric field it glows in a violet color.

What happens if you breathe in argon?
Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.
Is Argon an explosive?
Argon is neither flammable nor reactive. If a tank of argon is heated or punctured, the tank may rupture and cause physical injury. Argon is an element that exists as a gas in its natural form. Argon is a colorless, odorless gas.
Can argon kill you?
Argon can kill you if it replaces too much air and therefore decreases the partial pressure of oxygen too much. Argon can also kill you if you directly inject it into your bloodstream, causing a gas embolism. Argon is an inert gas and non-poisonous gas. It can kill human beings and animals due to asphyxiation.
Why is argon so expensive?
Argon is a noble gas (like helium) which means that it is completely inert. Argon will not readily react with any other substance. Since it is such a small percentage of the atmosphere Argon is many times more expensive than Nitrogen.
Does argon cause cancer?
Jersey Department of Health and Senior Services, Argon has not been tested for its ability to cause cancer in animals.
Is argon toxic to humans?
Argon is nontoxic and largely inert. It can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life. Inhalation of argon in excessive amounts can cause dizziness, nausea, vomiting, loss of consciousness, and death.
Can you lay an argon bottle down?
Propane and Butane bottles should also be stored and used upright, because of the point in the bottle the fuel is tapped from. Compressed gasses, like Oxygen, Argon, 75/25, or Tri-mix (examples of many) “can” be stored and used horizontally.
Is argon necessary for life?
Whether you know it or not, you’re breathing argon right now. But there’s no need to be alarmed: This colorless, odorless gas makes up a mere 0.94 percent of the air around you, and it’s so nonreactive that it has no effect on living organisms such as humans.
Why is life on Earth dangerous without argon?
With respect to life, essentially nothing. Argon is not used by any metabolic process, so no living thing would be affected by its absence. The total air pressure would decrease by 0.934%, which would not be enough to bother anything.
Can you breathe without argon?
We can breathe pure oxygen for unlimited time if the pressure is not too high; about 0.4 bar is okay. Argon is less narcotic and may be used at a pressure less than about 24 bar. Krypton is also narcotic at pressures above 3.9 bar. Neon is narcotic at very high pressure above 110 bar.
