its not elements as such so much as components, i.e. not chemistry but electronics more details here http://www.ieee-virtual-museum.org/collection/tech.php?id=2345819&lid=1

What replaced the vacuum tube?
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
Is vacuum tube ohmic or non-ohmic and why?
Vacuum tubes are non-ohmic devices
Can sound travel through vacuum tube?
Sound cannot travel through vacuum, but unless there is sufficient insulation, sound might travel through the material the tube is made of.
Why must there be a near vacuum in the tube of mercury barometer?
there must be vacuum in the mercury barometer because if air enters the tube the barmeter would become faulty as air pressure will change.
Who made the beam of electrons in vacuum tube?
This beam of electrons is emited by the cathode under voltage difference.
When was the three-electrode vacuum tube invented?
In 1907 American inventor Lee De Forest invented the three-electrode vacuum tube
Who invented the three-electrode vacuum tube?
In 1907 American inventor Lee De Forest invented the three-electrode vacuum tube
What computer component did the transistor replace?
the vacuum tube
What are the names of some old radio components?
Tube Choke Condensor Vibrator (used in HV battery supplies) Valve is another term for vacuum tube, used in old radios.
What gas is used in a vacuum tube?
A vacuum tube does not contain any gases. All the gases are evacuated from the tube and only vacuum is left.
What are the elements of a vacuum tube?
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
What is in a vacuum tube?
Millman's theorem
Where was vacuum tube was made?
who made the vacuum tubes
What replaced the vacuum tube?
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
How many KB is a vacuum tube?
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.
How many vacuum tube in one transistor?
There are no vacuum tubes in a transistor. A vacuum tube is an electronic device that uses a heated cathode in a vacuum to direct and control an electron stream to an anode, also known as the plate. The vacuum tube is old technology, but it is still used today, typically in high power applications such as transmitters. A transistor is an electronic device that uses solid-state semiconductors to similarly control an electron stream. The transistor is newer than the vacuum tube. It offers lower power, smaller size, easier use and other enhancements over vacuum tubes, within limits, of course, such as voltage and power.
What does vacuum tube mean?
an electron tube containing a near-vacuum that allows the free passage of electric current.
