Glass, just like any other physical material, has both of them, nortmally in
equal numbers. When a sample of glass picks up extra electrons, it appears
to be negatively charged, whereas when some of its electrons are stipped away,
it appears positively charged.

Glass is typically made up of silicon dioxide molecules, which do not have a net charge, so they have an equal number of protons and electrons. In general, the number of electrons in glass will vary depending on the size and composition of the glass structure.

If glass is covalently bonded are the electrons free to move and how is this related to the electrical conductivity of glass?
In glass, the electrons are not free to move due to the covalent bonds holding the atoms together. This lack of free-moving electrons leads to glass being an insulator with low electrical conductivity.
How can you make a glass surface to have a positive surface charge?
You can make a glass surface have a positive surface charge by rubbing it with a material that transfers electrons to the glass, such as a silk cloth or a piece of fur. This transfer of electrons can leave the glass with a net positive charge on its surface.
How many electrons does the element Be have in it?
4 electrons, 2 valence electrons
How many neutral electrons does argon have?
Electrons are always negative. There is no neutral electrons.
How many electrons does the element argon have?
Argon has 18 electrons.
Why is glass an insulator?
Glass has no free electrons to convey current.

What Do not permit electrons to flow through them?
Glass
Why does a glass rod get positively charged when rubbed with rubber?
electrons are transferred from glass to rubber
Why is glass transparent?
When the electrons in molecules are unable to absorb the energy of incident photon, the photon continues along its path. This happens in the case of glass, even though glass is not 100 percent transparent, as some of the photon energy is absorbed by the glass electrons.
What charge do you get if glass is rubbed with silk?
the silk will rub of the electrons on the silk, leaving the glass positively charged
Why does the amount of static charge continue to increase on a glass surface as you rub it?
Rubbing the glass surface creates friction, which causes the transfer of electrons between the glass and the material rubbing against it. This transfer of electrons leads to an accumulation of static charge on the glass surface. The more rubbing that occurs, the greater the charge build-up on the glass.
Electrons do not flow through glassglass is classified as?
Glass is an insulator.
What material is most difficult for electrons to flow through?
Insulators are materials through which electrons have the most difficulty flowing. This is because insulators have very few free electrons that are able to move through the material. Materials like rubber, plastic, and wood are good examples of insulators.
Which material is it most difficult for electrons to flow through?
glass
Will rubbing a silk cloth on glass cause electrons to move to the cloth?
Yes, rubbing a silk cloth on glass cause electrons to move to the cloth. As a result, glass rod acquires positive charge and silk acquires negative charge.
Is glass insulator or conductor?
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".
