It is the third most abundant element in the earth's atmosphere and makes up about 1%. 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. Continuously released into the air by decay of radioactive potassium-40. Pure form is obtained from fractional distillation of liquid air. nrHVOFG2V-c Argon
Moscovium was identified in 2004 by a team composed of Russian scientists at the Joint Institute for Nuclear Research in Dubna, and American scientists at the Lawrence Livermore National Laboratory.

The team reported that they bombarded americium-243 with calcium-48 ions to produce four atoms of moscovium.

These atoms decayed by emission of alpha-particles to nihonium in approximately 100 milliseconds. Named after Moscow Oblast where Dubna is located 18 1894 Sir William Ramsay, Lord Rayleigh Scotland From the Greek word "argos" meaning "inactive"
