What else can I help you with?
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.
What factor was used to determine conductivity of matter?
No
What is the conductivity of K?
The conductivity of potassium (K) is high because it is a metal and readily conducts electricity due to the presence of free-moving electrons in its atomic structure.
Which metal has the highest electrical conductivity value?
Silver has the highest electrical conductivity of all metals. It is highly conductive due to its free-moving electrons that allow electricity to flow easily through it.
Why does a metal have good conductivity?
Metals have good conductivity because of the way their atoms are arranged. Metals have a "sea of delocalized electrons" that are free to move through the lattice of metal ions, allowing for easy flow of electric current. This mobility of electrons is key to good conductivity in metals.
Importance of photoconductivity?
to increase the conductivity of materialsno.of free electones and holes increase by conductivity
What does electrical conductivity of a substance depend on?
The electrical conductivity of a substance depends on the presence of free electrons or ions that are able to carry electric current. Materials with high electrical conductivity typically have a high number of free electrons or ions that can move easily in response to an electric field. Conversely, materials with low electrical conductivity have fewer free charge carriers available to conduct electricity.
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.
What is the conductivity of calcium carbonate?
Calcium carbonate is an insulator and has low electrical conductivity due to the absence of free-moving electrons in its structure. This means that it does not conduct electricity well in its solid form.
What properties of liquids will affect its conductivity electricity?
The conductivity of a liquid is affected by its concentration of ions, which are charged particles that carry electric current. The type and number of ions present in the liquid will determine its conductivity. Additionally, temperature can also impact the conductivity of a liquid, with higher temperatures generally leading to higher conductivity due to increased ion mobility.
What factor should change in electrical conductivity of metals and non metals?
In metals, electrical conductivity increases with higher number of free electrons, which can be influenced by factors like temperature and impurities. In non-metals, electrical conductivity is generally lower due to lack of free electrons, but can increase with doping or introduction of impurities.
What solutions will have the highest electrical conductivity 0.1m nacl 0.1m bacl2 0.1m alcl3?
The solution of 0.1M NaCl will have the highest electrical conductivity among the three options provided. This is because NaCl dissociates completely in water to produce more free ions, which increases the conductivity. BaCl2 and AlCl3 do not dissociate as completely as NaCl, resulting in fewer free ions and lower conductivity.
What factor was used to determine conductivity of matter?
No
What is molar conductivity at infinite dilution?
Molar conductivity at infinite dilution refers to the maximum conductivity of an electrolyte solution when it is extremely dilute. At this limit, all ions are completely dissociated and free to conduct electricity independently. This value is used to compare the conducting abilities of different electrolytes irrespective of their concentrations.
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 conductivity for beryllium?
The thermal conductivity of beryllium is 200 W/m.K.
What are the differences between metal semiconductor and insulator?
Metal is a good conductor of electricity due to the presence of free electrons, while semiconductor has conductivity in between metal and insulator and its conductivity can be controlled by doping. Insulator has very low conductivity as it lacks free electrons for conduction.
