– Hydrogen is a non-metal, but good conductor of electricity only at very high pressure.
Is hydrogen a conductor or insulator of electricity?
Diamond is an insulator.
Electrical Type of the elements.
Is good or poor conductor of electricity?
Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood.
Is hydrogen a good insulator?
The band-gap of hydrogen in its uncompressed state is about 15 eV, making it an insulator but, as the pressure increases significantly, the band-gap gradually fell to 0.3 eV.
Which element is the poorest conductor of electricity?
Of the five choices given, fluorine is the least conductive of these as it actually is an insulator. Metals, e.g., calcium, cobalt, sodium, by their…
Is hydrogen conductive of electricity?
Above 220 GPa, hydrogen became opaque and electrically conductive. At 260-270 GPa, hydrogen transformed into a metal as the conductance of hydrogen sharply increased and changed little on further pressurizing up to 300 GPa or cooling to at least 30 K; and the sample reflected light well.
What is the best conductor of electricity?
What Metal is the Best Conductor of Electricity?
- Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. …
- Copper. One of the most commonly used metals to conduct electricity is copper. …
What are poor electrical conductors?
Materials that are poor conductors of electricity are called insulators. Some examples are wood, glass, plastics, non-metal elements that are polymers of hydrocarbons. … So among the following options aluminum, silver and copper are metals and these are good conductors of electricity.
What are poor conductors of electricity give examples?
Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies. Cables are wires covered in plastic so we can handle them safely.
Which is the poor conductor?
A poor conductor means that the substance will not easily conduct heat or electricity (or both) as easily as a conductor. … Some other examples of poor conductors of electricity are mica, paper, wood, glass, rubber, Teflon, etc. Some examples of poor conductors of heat are air, lead, etc.

Interesting Facts about Hydrogen
- Scientists estimate that Hydrogen makes up over 90 percent of all the atoms in the universe.
- It is the only element that can exist without neutrons.
- Hydrogen becomes a liquid at very low temperature and high pressure. …
- Around 10 percent of the mass of the human body is hydrogen.
What metals are not good conductors?
Mercury and Gallium are not as good conductors as most metals (but they are good conductors). Their conductivities are two orders of magnitudes less than most metals. Note that mercury/gallium still are better conductors than graphite.
What materials are not good conductors of electricity?
Materials that do not let current flow easily are called insulators. Most nonmetal materials such as plastic, wood and rubber are insulators.
