(Argon)是一种化学元素,在希腊语有「不活泼」的意思,由它的特性而来。它的化学符号是Ar,它的原子序数是18,在室温下是无色无味气体。由于原子外层轨道充满电子,因此它不容易发生化学反应,是一种惰性气体。把它放电时呈紫色。已知的氩的同位素共有14种,包括氩33至氩46。氩占大气体积的0.93%,是地球大气中第三多的气体,也是在大气中含量最多的惰性气体。它的三相点以国际实用温标定义为83.8058K。

Argon 氩

Vial containing a violet glowing gas
A small piece of rapidly melting solid argon.
Lord Rayleigh's method for the isolation of argon, based on an experiment of Henry Cavendish's. The gases are contained in a test-tube (A) standing over a large quantity of weak alkali (B), and the current is conveyed in wires insulated by U-shaped glass tubes (CC) passing through the liquid and round the mouth of the test-tube. The inner platinum ends (DD) of the wire receive a current from a battery of five Grove cells and a Ruhmkorff coil of medium size.
Space-filling model of argon fluorohydride.

Argon is a chemical element with symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv) more than twice as abundant as water vapor (which averages about 4000 ppmv, but varies greatly), 23 times as abundant as carbon dioxide (400 ppmv), and more than 500 times as abundant as neon (18 ppmv). Argon is the most abundant noble gas in Earth's crust, comprising 0.00015% of the crust.
