What else can I help you with?
Is the electrical conductivity of molten metals high or low?
Metals are already good electrical conductors, and melting metals increases their electrical conductivity. All that heat (thermal energy) allows electrons a lot more mobility so they can more effectively contribute to current flow.
Are all metals electrical conductor?
Yes, metals are generally good electrical conductors due to the presence of free electrons that can move in response to an electric field. However, not all metals are equally good conductors, and some metals have higher electrical conductivity than others.
Metals are known to?
metals are known to be a good conductor of heat and electricity.
What two properties of metal make them useful materials for the electrical wiring at home?
Metals have high electrical conductivity, allowing electricity to flow easily through them. They also have good ductility, meaning they can be easily shaped into wires without breaking, making them ideal for conducting electricity in homes.
What is responsible for the good electrical conductivity of metals?
The good electrical conductivity of metals is due to their loosely held electrons, which are free to move throughout the metal structure when a voltage is applied. This movement of electrons allows for the flow of electric current with little resistance.
Four properties of metals?
- have lustre (shine) - are malleable/ductile (can be shaped or molded without breaking) - are good thermal (heat) conductors - are good electrical conductors - have high density

Is responsible for the good electrical conductivity of metals?
The metallic bonding which is basically a "sea" or cloud of electrons.
Are all metals electrical conductor?
Yes, metals are generally good electrical conductors due to the presence of free electrons that can move in response to an electric field. However, not all metals are equally good conductors, and some metals have higher electrical conductivity than others.
Metals are known to?
metals are known to be a good conductor of heat and electricity.
Do substances with good electrical conductivity conduct heat well?
Yes, substances with good electrical conductivity typically also conduct heat well. This is because the movement of electrons that allows for good electrical conductivity also facilitates the transfer of thermal energy. Materials like metals, which are good conductors of electricity, are also good conductors of heat.
Do metals have electric conductivity?
Type your answer here... due to free electrons metals are good conductor
Do elements that have high electric conductivity also have high thermal conductivity?
Not necessarily. While there is some correlation between electrical and thermal conductivity in metals, there are exceptions. For example, diamond is a good thermal insulator despite being a good electrical insulator. Additionally, materials like ceramics can have low electrical conductivity but high thermal conductivity.

What does the electron sea model of metallic bonds help you to explain?
Properties of metals as high boiling point, high melting point, malleability, ductility, electrical conductivity, thermal conductivity, lustre are explained by the theory of metallic bonds.
What are properties of metal?
Metals are typically shiny, malleable, and ductile. They have high thermal and electrical conductivity, and are usually solid at room temperature (except for mercury). Metals also tend to be dense and have a metallic luster.
What is responsible for the good electrical conductivity of metals?
The good electrical conductivity of metals is due to their loosely held electrons, which are free to move throughout the metal structure when a voltage is applied. This movement of electrons allows for the flow of electric current with little resistance.
