True.
No, it is an insulator because it DOES NOT allow the flow of electrons.
Glass is an insulator, as it DOES NOT conduct current. It is a material which has no free electrons available to flow as electrical current. Conductors, like copper or aluminum, have free electrons, or electrons in the outer shells of their atoms that are easily knocked loose. These electrons flow from negative to positive when an electrical potential (voltage) is applied across the material. We call the flow of electrons "current".

An insulator or a dielectric.AnswerInsulators behave in the way they do because they contain insufficient numbers of charge carriers to support conduction. It has nothing to do with electrons being 'unable to flow easily'!
Glass is an insulator.
It is a insulator. The glass does not have free electrons to flow as current, and the air in the tube is also an insulator.

An insulator is a material through which electrons do not easily flow. Insulators have a very high resistance.AnswerInsulators behave in the way they do because they contain insufficient numbers of charge curriers to support conduction.

A good conductor of electricity is copper, which allows electrons to flow easily, while a good insulator is rubber, which restricts the flow of electrons due to its high resistance.
A conductor is a material that allows the flow of electrical current, while an insulator is a material that resists the flow of electrical current. Conductors have high conductivity, allowing electrons to flow easily, whereas insulators have low conductivity, preventing the flow of electrons.
Cardboard is an insulator. It does not conduct electricity efficiently due to its high resistance to the flow of electrons.
