Most vacuum tubes have real silver inside. Since silver is going way up. these tubes are becoming valuable

There is no gas inside it is a vacuum tube.
the vacuum tube
It means that the glass envelope has leaked and is no longer a vacuum. Air inside has oxidized the getter. They generally no longer work in this condition.
Vacuum tubes are typically evacuated of gases to create a vacuum inside. However, some specialized vacuum tubes may use inert gases like argon or neon to improve performance or provide specific characteristics.
It's almost a vacuum, it contains no air.
No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
Millman's theorem
who made the vacuum tubes
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
an electron tube containing a near-vacuum that allows the free passage of electric current.
