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.

If glass is covalently bonded are the electrons free to move and how is this related to the electrical conductivity of glass?
No the electrons are not free to move. This means that the electrical conductivity will be relatively low. -jk
How many electrons does the element Be have in it?
4 electrons, 2 valence electrons
How many electrons does FM have?
100 electrons
How many neutral electrons does argon have?
Electrons are always negative. There is no neutral electrons.
How many electrons are in chlorine?
there are 17 electrons in chlorine. and 7 of them are valence electrons.
Why is glass an insulator?
Glass has no free electrons to convey current.
What Do not permit electrons to flow through them?
Glass
Electrons do not flow through the molecular structure of glass for this reason glass is classified as?
an insulator
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
Electrons do not flow through glassglass is classified as?
Glass is an insulator.
What material is most difficult for electrons to flow through?
glass
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".
