Model Planetari Bohr Argon (Ar)
Rajah Dot Lewis Argon (Ar)
Description
Colorless, odorless, tasteless noble gas. It is the third most abundant element in the earth's atmosphere and makes up about 1%.
Uses
Used in lighting products. It is often used in filling incandescent light bulbs. Some is mixed with krypton in fluorescent lamps. Crystals in the semiconductor industry are grown in argon atmospheres.
Sources
Continuously released into the air by decay of radioactive potassium-40. Pure form is obtained from fractional distillation of liquid air.
Pronounciation (English)
AR-gon
