40 Ar, because of its weight its very close to 40g/mol
Yes, but the solubility is very low.
No, phosphorus is more reactive than argon. Phosphorus readily reacts with other elements to form compounds, whereas argon is a noble gas with very low reactivity due to its stable electron configuration.
The element Argon has 8 Isotopes argon-35, argon-36, argon-37, argon-38, argon-39, argon-40, argon-41 and argon-42.The stable isotopes of argon are:argon-36, 0.34%argon-38, 0.06%argon-40, 99.60%Of the radioactive isotopes argon-39 has the longest halflife at about 260 years, all the others have halflives measured in days or much less.
According to wikipedia, argon has 24 known isotopes. 40Ar is most abundant at about 99.6% of natural argon.
Argon is a noble gas, and very non-reactive. Argon fluorohydride, HArF has been synthesized, but is only stable at very low temperatures.
Argon does very little to help us live.
Argon is an inert and non toxic gas, there is a very small amount of Argon in the air we breath, and is not normally considered dangerous.
An oxide of argon is not known and very probably is impossible.
Argon is sparingly soluble in water. It has very low solubility and does not react with water.
The electron affinity of argon, like all noble gases, is 0, or very close to it, due to its chemical inertness.
Argo in greek means lazy, since argon is a noble gas it does not react very much.
Argon is a colorless, odorless, and tasteless gas that is non-reactive. It is the third most abundant gas in the Earth's atmosphere, making up about 1% of the air we breathe. Argon is commonly used in industry for welding, as a shielding gas in metallurgy, and in lighting applications.
Not a great deal. It is a very inert gas.
Argon is a noble gas, which means it is very stable and does not typically form bonds with other elements. It already has a full outer electron shell, so it is considered inert and does not readily undergo chemical reactions.
When it was first created - in stars during the very early stages of the universe.
No, it is very low. Argon has a melting point of −189.3°C
