Argon is stable. Calcium is reactive.
There is no compound that forms between argon and calcium.
Argon is a very stable element, and isn't very reactive.
Because the valency shell for its electrons is full.
The elements from most reactive to least reactive are: Chlorine, Oxygen, Argon, and Neon.
The elements from most reactive to least reactive are: Chlorine, Oxygen, Argon, and Neon.
No, it is not.
No, argon is not a highly reactive gas. It is stable.
Argon is a very stable element, and isn't very reactive.
Because the valency shell for its electrons is full.
Argon is a noble gas, and very non-reactive. Argon fluorohydride, HArF has been synthesized, but is only stable at very low temperatures.
Argon has completely filled valence orbitals and hence is unreactive. Sodium has one valence electron. If sodium loses this electron it will attain the stable electron configuration of the nearest noble gas (argon) and hence is reactive.
Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
calcium is not stable because the outer most atomic level is not full the only elements that are stable are the nobel gasses(helium,neon,argon,krypton,xenon,and radon)
Calcium is pretty reactive and is not stable in air; it fairly rapidly corrodes, forming calcium oxide (it's reactive enough to even react to some degree with elemental nitrogen, which is generally fairly inert, forming calcium nitride as well). It's also flammable, though somewhat difficult to ignite.If you meant in the radioactive sense, there are five stable isotopes of calcium, and one (calcium-48) that's so long lived that it can be treated as stable for practical purposes, having a half-life of on the order of ten million million million years.
Yes you are correct, potassium being an alkali metal is definitely more reactive than argon which is a noble gas (group 18 element). Potassium reacts violently with just water while argon is very inert and stable, which is why it remains in the atmosphere as a monatomic element.
Ca2+ is a cation formed by Calcium to become stable and attain the noble gas configuration of Argon. Calcium forms this cation by losing two electrons

The elements from most reactive to least reactive are: Chlorine, Oxygen, Argon, and Neon.
