Argon is in Group 18, the unreactive Noble Gases.
Argon's atomic number is 18, which means it has 18 protons in its nucleus.
Argon's melting point is 83.80 Kelvin, −189.35 °Celsius, or −308.83 ° Fahrenheit
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 a Noble or Non-reactive gas otherwise we'd all be dead by now as about 1% of the air we breathe in is Argon along with 21% Oxygen.
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.
Argon is a non metal element. Atomic mass of it is 39.94.
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 atoms have 18 protons which is similar to the number of electrons.
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.
