What is the boiling point of argon at?
Atomic weight of Argon is 39.948 u or g/mol. Melting point of Argon is -189,4 °C and its the boiling point is -185,9 °C. About Argon. Argon is a gas without color and odor, which is one of the noble gases and is totally not reactive with other elements of the Periodic Table.
How many isotopes of argon are there in the world?
About Argon. Argon is a stable and largely inert element that has yet to produce any known compound at room temperature, and only one compound (HArF) at very low temperatures. This compound does not have any practical application outside of fundamental scientific research. Three isotopes of argon are naturally occurring: 36 Ar, 38 Ar,…
Why is argon considered to be an odourless gas?
It is odourless, colourless gas that is totally inert into other substance. Under extreme conditions, argon can form certain compounds even though it is a gas. It is characterized by same solubility level in water as that of oxygen. It has low thermal conductivity.
