- Density: 0.0017837 G/CCM
- Atomic radius: 71 pm
- Current Cost: 50 cents/100 gs
- Common isotopes: 36Ar, 38Ar, 40Ar
Used when an inert atmosphere is needed. Used in production of titanium and other reactive elements. It is used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.
Used in fluorescent tubes and low-energy light bulbs. A low-energy light bulb often contains argon gas and mercury. When it is switched on an electric discharge passes through the gas, generating UV light. The coating on the inside surface of the bulb is activated by the UV light and it glows brightly.
Chemical properties:
Chemically inactive
argon fluorohydride (HArF), discovered in 2000. Does nothing
