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
Which of the following is not considered a characteristic or property of a gas?
it is lighter than air, typically found in the upper regions of a confined space
Do metals have electric conductivity?
Type your answer here... due to free electrons metals are good conductor
Why is the electrical conductivity low in argon?
Argon has completely filled orbitals and satisfies octet rule. Hence the configuration is stable and has low electrical conductivity due to the absence of free / unpaired electrons.
The valence electrons found in metallic bonds give metals which characteristics?
Free- Roaming electrons, and conductivity
Importance of photoconductivity?
to increase the conductivity of materialsno.of free electones and holes increase by conductivity

On what does conductivity in a metallic wire depend?
Free electrons only
Do neutrons determine the conductivity of the atom?
no, but they determine if it is an isotope or not
What materials are partially conductive?
conductivity is a result of free electrons meaning that they can be riped away fast and the temperature of the material. a colder material has a lower resistance and higher conductivity. materials like metallic oxides have low conductivity and materials like pure copper and aluminum have high conductivity.
What is the difference between thermal and electric conductivity?
Electrical conductivity is flow of electrons between two different points having different electric potentials. Thermal conductivity is flow of electrons between two different points having different temperatures. Electrical Conductivity in solids, is purely based on number of free electrons (number of free electrons and holes in semiconductors). But thermal conductivity is based on number of free electrons and also phonons. Electrical conductivity in liquids and gases is also depends on number of free electrons but thermal conductivity in liquids and gases is because of molecular collision.
Which of the following is not considered a characteristic or property of a gas?
it is lighter than air, typically found in the upper regions of a confined space
What does electrical conductivity of a substance depend on?
how much free charged ions there are in a solution
Why gold is good conductor of electricity?
The conductivity (how well a material conducts) of a material depends on the density of its free electrons (number of free electrons per unit volume). The best metal conductor is silver. Copper's conductivity is 95% that of silver. Gold's conductivity is 65% that of silver. So, as you can see, gold is by no means the 'best' conductor.
Why is wood a poor cunductor?
conductivity closely relates to the number of free electrons , and in the wood material the electrons are not present in free state.
How can a person find information on thermal conductivity?
Information on Thermal Conductivity can be found on the internet. Leigh University, as well as many other colleges are a great source of reliable free information.
