All matter has mass - does all mass have matter? ;-)

Rapid oxidation.

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.
Argon is cheapest.
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?
you can ad a small amount of gas to a vacuum and it will still be in a
vacuum....
Well, there's clearly no way to test this
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

the word "vacuum" to the people "vacuuming" carpets, and just specify parts
per cubic kilometer when we want to be specific and scientific.
Don said: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.,
