Argon was discovered in 1894 by Lord Rayleigh and Sir William Ramsay while studying atmospheric gases.
Argon makes up nearly 0.93% of Earth's atmosphere, making it the third most abundant atmospheric gas after nitrogen and oxygen.

Argon is used in welding, incandescent light bulbs, scientific instruments, semiconductor manufacturing and special industrial atmospheres.
Argon generally does not react with other elements and remains chemically independent.
Argon has virtually no natural enemies because it is one of the most chemically stable elements.
Electronic Configuration: 1s² 2s² 2p⁶ 3s² 3p⁶
Argon's complete outer electron shell makes it extremely stable and chemically inert.
The name Argon comes from a Greek word meaning "inactive" or "lazy," reflecting its reluctance to react chemically.
Argon glows with a beautiful blue-violet color when electricity passes through it. It is often used in decorative lamps and plasma displays.
Argon provides a protective atmosphere during welding, preventing hot metals from reacting with oxygen and nitrogen in the air.
Argon is widely used during semiconductor and microchip manufacturing because its inert nature protects delicate materials.
Scientists use argon in plasma physics, particle detectors, laser technology and advanced industrial processes.
Argon is produced by radioactive decay processes and stellar nucleosynthesis. It is found throughout the universe and in planetary atmospheres.
Argon rarely forms compounds under normal conditions.
