Argon's atomic number is 18, which means it has 18 protons in its nucleus.
Argon has a melting point of -189.3°C or -308.7°F.
Argon's low melting point is due to its weak van der Waals forces between atoms, as it is a noble gas with a monatomic structure. These weak forces require less energy to overcome, resulting in a lower melting point compared to other elements with stronger bonds.
Argon is an inert gas and does not react with oxygen under normal conditions. Argon is stable and non-reactive, which makes it useful in applications where a non-reactive atmosphere is required.
The family name for bromine is the halogen family.
Helium, Xenon, Neon, Krypton, and Radon.
Ar
It is 87.3 K.
There are three natural isotopes.
The atomic mass of argon is approximately 39.95 atomic mass units.
For most people there is absolutely no reason to buy any argon in their lifetimes.
Argon is very unreactive as it is a noble gas. Its common oxidation number is zero.
argons, groans, orangs, organs, sarong
Ar 40 is the most common isotope, accounting for 99.6% of the total (by weight).
Argon's atomic number is 18, which means it has 18 protons in its nucleus.
Argon is a gaseous element, and it is allowed in the TWL and SOWPODS lexicons. Also, it is definitely legal to pluralize words in Scrabble.
Argon atoms have 18 protons which is similar to the number of electrons.
