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.

How does thermal conductivity differ from electric conductivity?
On deals with heat transmission (diamond is great at that) the other transmission of electrons (diamond is very poor at that)' Most metals are fairly good at both.
A property not associated with metal are electric conductivity?
Low Melting Point. Most metals have high melting point and are solids at room temperature.
What is the relation between hardness and conductivity?
Resistivity R is the inverse of conductivity G, R=1/G.
Why is silver more conductive than gold?
Conductivity is related to the size of an atom - the bigger the atomic radius, the easier it is to pick electrons off the edge of the atom. Silver has a larger atomic radius (160 pm) than gold (135 pm), despite the fact that gold has more electrons that silver. One caveat though is that in the presence of oxygen silver will corrode and thus become a worse conductor than gold, Gold on the other hand (except under certain extreme conditions) does not corrode, that's why electrical contacts are often gold tipped, to prevent signal degradation do to corrosion.
Why Sodium is softer than copper but both are good conductors of electricity?
In sodium and copper it is the s electrons delocalised accross the lattice that contribute to the electrical conductivity. The extra bonding due to d orbitals in copper, a transition metal, contributes to its hardness and higher melting point . Both sodium and copper have metallic bonds. Sodium is an alkali metal and there are no d electrons, wheres copper is a transition metal. In the alkali metals the only force of attraction between the metal atoms is due to the delocalisation of the s electrons. In transition metals there is an extra attraction due to the d electrons. Copper has one of the lowest heats of formation of the transition metals the d electrons contribute less than in the lighter members. Hardness is a poor measure IMHO of metallic bond strength, as hardness can be related to the density of lattice dislocations.
How are conductivity and concentration of a salt solution related?
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.
Why is electrical energy is a kind of kinetic energy?
It is related to the movement of electrons (or other charged particles).
How is electrical and nuclear energy related?
Electrical energy is the energy generally stored in electrons and their movement. Nuclear energy is the energy stored with an atom. Electrons are a fundamental part of most atoms, thus nuclear energy also contains direct electrical energy.
How does thermal conductivity differ from electric conductivity?
On deals with heat transmission (diamond is great at that) the other transmission of electrons (diamond is very poor at that)' Most metals are fairly good at both.
Which has lowest thermal conductivity?
silica Aerogel Refer to the chart from the Wikipedia article on thermal conductivity in related links.
How conductivity of water related with concentration?
pure water is insulator.
Which metal has the highest conductivity?
At room temperature, silver has the highest electrical and thermal conductivity of all the (known) metals. Note that diamond, an allotrope of carbon, is a poor electrical conductor but is several times better as a thermal conductor than silver. Carbon is a nonmetal, of course, but it was worth mentioning as both a comparison and a curiousity.
What is most related to electrons?
valence electrons
A property not associated with metal are electric conductivity?
Low Melting Point. Most metals have high melting point and are solids at room temperature.
What are thermal properties in science?
Some are latent heat, temperature, thermal conductivity, stability (as opposed to explosiveness), insulation ability which is related to thermal conductivity, and others.
Do all metals conduct electricity?
All metals conduct electricity as the outer electrons are esenentialy "free" and not constrained to being with one particular atomic nucleus. As a result electrons coming in from a sources displace electrons at the far end of the metallic objectAll metals conduct electricity because by definition the valence band electrons in metal atoms become delocalized, forming an "electron gas" that flows freely within the bulk of the material.
Would tin be a good conductor?
Tin does conduct electricity, but it is only 15% as conductive as copper. See related link for a table of metals and their electrical conductivities. If you meant heat conductivity, then it is about 18% as conductive as copper. I'll post a link to that, as well.
