Fun Facts About Argon. Argon is one of the many elements in the Periodic Table. Its normal phase is gas, and it is in the family of Noble Gases. Its symbol is Ar., and its atomic number is eighteen. There are also eighteen protons, twenty-two neutrons, and eighteen electrons in argon. This element boils at -186.0 degrees Celsius and melts at -189.3 degrees Celsius.
For this reason, Minimax decided in favour of argon after long reflection. Argon is a readily available inert gas which is present in the earth's atmosphere in quantities of 0.93 % by volume. It is chemically inert and is not known to have been used for fire extinguishing purposes in the past. Argon will remain stable even in high-temperature environments which makes it suitable to be b Argon has zero ODP. 0 Argon has zero GWP As well as toxic gases formed by the fire, the possible effects of hypoxia on humans must be considered when a fire is to be extinguished by means of an inert gas.
