Is argon a neutral?
Under standard conditions argon is an odorless and colorless gas. Argon has been found to form one neutral compound with fluorine and hydrogen called argon fluorohydride (HArF).
Can argon be a liquid?
Although used more commonly in the gaseous state, argon is commonly stored and transported as a liquid, affording a more cost-effective way of providing product supply. Liquid argon is a cryogenic liquid. Liquid argon has a boiling point of –303°F (–186°C).

What is AR periodic table?
argon (Ar), chemical element, inert gas of Group 18 (noble gases) of the periodic table, terrestrially the most abundant and industrially the most frequently used of the noble gases.
What is argon chemical formula?
Ar
Argon Chemical Formula The formula for Argon Gas is Ar. It has the atomic number 18 and is a noble gas. The gas utilized in fluorescent tubes is monatomic argon. Argon Gas has the molecular formula Ar.
How is argon isolated?
Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon.
Is argon stable or unstable?
The outermost (valence) shell of argon has eight electrons, making it exceedingly stable and, thus, chemically inert.
Why is argon a stable element?
Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. The complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding with other elements.
