All metals are good conductors of heat and electricity.
Aluminum, copper, silver, gold, and other exhibit this general characteristic.
Metals, like other solids have atoms confined to regular positions. The vibration of these atoms imbues them with kinetic energy and when atoms in one region vibrate faster than in another, the faster region has a higher temperature. If a material has a region of high temperature and a region of low temperature, then the vibrations of atoms with a region with more kinetic energy will interact with neighboring atoms and they will acquire more of the energy. This process continues and eventually the colder regions get some of the energy from the warmer regions. After a long time, an insulated object will distribute energy by this process of interactions with neighboring atoms and the temperature in the object will become uniform.
The process of conducting heat described above works in all materials, liquid, gas or solid with atoms of higher kinetic energy transferring energy to neighboring atoms of less kinetic energy.
The process of heat moving from hot to cold is called thermal conduction. Some materials are better at it than others and that depends on the makeup of the material.
But, metal have something special going for them so they get a little extra boost in the thermal conductivity arena. Metals have a lot of electrons that are not strongly bound to the atoms. (The have have strongly bound electrons too, but a typical metal has one or two per atom that or not strongly bound.) In fact, these weakly bound electrons are not even associated with one atom in particular, but are nearly free to have their range extend throughout the conducting material.
A very significant amount of heat energy flow is attributable to the nearly-free electrons in a metal. The mechanism is a little complicated because the elecrons are moving very fast, even when no electricity is flowing. Not only are the electrons able to gain energy in the hot regions and move to the cold regions easily, the movement of the atoms affect not one electron but the entire cloud of nearby electrons and so can effectively extend the range of influence of one vibrating atom to atoms further away.
Insulators do not conduct heat and are therefore non-metals. Metals do conduct heat, and vey well may i add. But, for the record, you're thinking of electricity. Potatoes conduct heat, and they're not metals. Anyone who has held a lump in their hand will tell you that playdough conducts heat, in fact, rather a lot of other materials conduct heat and water also conduct heat
No, most metals are electrical conductors. This means that most metals will conduct an electric current in the presence of an electric field.
Yes they are, I'm trying to find out why though.
metal conducts electricity because it allows electrons to move freely as well as it has free electrons, unlike insulators(non-metals) which do not have free electrons. When the electrons are allowed to move freely in a substance, it is a good conductor and allows electric charge to flow.
Non-metals generally are not good conductors of heat or electricity, have a dull surface, are brittle to the touch, and are not easily molded into shapes.
No, not all electrical conductors conduct current equally well. The ability of a material to conduct electricity is determined by its conductivity, which can vary depending on factors such as the material's composition, structure, and temperature. Metals like copper and silver are known for their high conductivity, while materials like plastic and rubber have low conductivity.
Materials such as rubber, wood, plastic, and glass do not conduct electricity as well as metals do. These materials have high electrical resistance compared to metals, which allows for minimal to no flow of electric current through them.
Some materials that conduct electricity include metals like copper, silver, and gold, as well as carbon in the form of graphite. In addition, solutions containing ions, like saltwater, can also conduct electricity.

Materials that conduct heat well include metals such as copper and aluminum, as well as materials like graphite and carbon steel. Materials that conduct heat poorly include wood, rubber, and plastic, as they have low thermal conductivity. insulating materials like foam and fiberglass also have poor heat conduction properties.
all metals conduct electricity but alumiun doesn't conduct it as well as others all metals conduct electricity but alumiun doesn't conduct it as well as others
Materials that conduct electricity well include metals such as copper, aluminum, and silver. In contrast, insulating materials like rubber, plastic, and glass do not conduct electricity. Some fabrics that can conduct electricity are conductive fabrics made by weaving metal threads with conventional fibers.
All.
Yes
WoodGlassWaxetc.
yes. metals conduct heat and electric current well.
Yes, although they won't conduct it as well as regular metals. Semi-metals have characteristics of both metals and nonmetals.
