Argon is cheapest.
Rapid oxidation.

Well, no. Without gas, the filament evaporates faster.

With atmospheric fill however, it oxidizes and burns out quickly.

Sure there is. A given volume of space will enclose a perfect
vacuum as long as no matter enters that volume.

Zero _particles_, actually. And no, some vacuums are perfect some
of the time. For example, take a cubic meter of space out there
somewhere where a lone hydrogen atom goes zipping through that
volume every hour or so. During the time the atom is in there the
vacuum won't be perfect, but during the times isn't in there it
_will_ be a perfect vacuum.

Well, there's clearly no way to test this - aren't the Voyagers and
Pioneers and stuff still hitting particles?

But, really, I don't know to theorize just how hard of a vacuum could
be had in, say, intergalactic space.

Thanks,
Rich

** Rediculous crapology.

Typical of Tim the TROLL !!

Nitrogen is 80% of the air we breath and is dirt cheap.

Might I suggest that the question of "what situation can I call a vacuum
and
not have people jump all over me" is a political matter?


** Sure - if you want to look like a complete FUCKWIT you can.

But Nitrogen isn't very inert. It forms bonds with many elements. There is a
reason that they call Argon, Krypton, etc. the "Noble Gases", they don't
form bonds very easily.

you can ad a small amount of gas to a vacuum and it will still be in a
vacuum....

no, it'll be a partial vacuum.


Bye.

Aren't you the only person who would call Nitrogen an Inert Gas? I guess you
can't learn much from talking with dingoes in the Outback, so while you are
here you can look and learn.

Might I suggest that the question of "what situation can I call a vacuum and
not have people jump all over me" is a political matter? Maybe we can leave
the word "vacuum" to the people "vacuuming" carpets, and just specify parts
per cubic kilometer when we want to be specific and scientific.

I believe it to be an inert gas too.

Did I miss something?

Nitrogen -
Atomic number - 7, sits between carbon and oxygen at period 15, a group
5 element according to kalzium.
As it generally has 5 electrons in its outer shell in its natural state,
I would imagine its relatively reactive (at least as much as phosphorous).

According to wikipedia:
"Nitrogen is a non-metal, with an electronegativity of 3.0. It has five
electrons in its outer shell and is therefore trivalent in most
compounds. Nitrogen condenses at 77° K at atmospheric pressure and
freezes at 63° K. Liquid nitrogen is a common cryogen."

Is it inert? hardly.
Is it a noble gas? certainly not - noble gasses have full outer electron
shells.
Examples are Helium, Neon, Argon, Krypton, Xeon and Radon
(pick the one you were really thinking of)

You missed nitrates, nitrides, ammonia (NH3), Life Itself, etc., etc., etc.,

inert gas


or noble gas, any of the elements in group 0 of the periodic table. In order
of increasing atomic number they are: helium, neon, argon, krypton, xenon,
and radon. They are colorless, odorless, tasteless gases and were once
believed to be entirely inert, i.e., forming no chemical compounds; however,
some compounds of these elements have been produced, i.e., fluorides of
krypton, xenon, and radon. The low chemical activity of the inert gases is
due to the fact that their outermost, or valence, electron shell is
complete, containing two electrons in the case of helium and eight in the
remaining cases. The inert gases are sometimes called the rare gases,
although argon is not rare (it makes up about 1% of the atmosphere) and
helium is commercially extracted from natural gas and the atmosphere.

All DNA bases have atomic nitrogen in them, amino acids also
have atomic nitrogen in them. By that statement what we're saying is if you
have nitrogen in its simplest form, the atomic form, it's much more
reactive and can more easily form complex prebiotic organics in space.

Nitrogen is reactive, not inert.

NF3

Chlorides
NCl3

Well, about 80% of what you're breathing at this instant is nitrogen.

Actually, "fixing" nitrogen - causing it to combine with other
elements, as to make ammonia, for example - is relatively difficult.
Until early in the 1900's, it was considered the exclusive domain of a
smallish range of bacteria.

As far as things like light bulbs go, nitrogen is pretty much inert.
Some small amount of nitrogen compounds are formed inside internal
combustion and jet engines, where conditions are fairly intense.
