Yes, both
That is correct, yes.
All metals except mercury can conduct both heat and electricitythrough them very well. Metals have big pool of electrons and specially surface electrons that are easy to move can conduct electricity. All metals are shiny. All metals are ductile. Most of the metals can be mixed together to produce alloys.
Most metals conduct electricity, as does carpet and most liquids - Pure water doesn't.
Most non-metals are in fact considered to be non-conductors. Some non-metals however do have the ability to conduct heat and electricity.
A metal such as copper or aluminum is likely to conduct heat well. Metals generally have high thermal conductivity due to the arrangement of their atoms allowing for efficient heat transfer.
Gold. Any metal, actually; most metals conduct both heat and electricity quite well.
None are more metallic. Metallic is a way of describing a metal in general.
The best mediums to conduct electricity are metals like copper, silver, and gold due to their high conductivity properties. Other good conductors include aluminum, iron, and graphite. materials like rubber, plastic, and glass are insulators and do not conduct electricity.
Yes, most alloys are good conductors of heat and electricity. This is because alloys are made by mixing different metals together, which creates a structure that allows the flow of heat and electric charge more easily compared to pure metals.
Graphite is an example of a substance that can conduct electricity but is a poor conductor of heat. This is because of its unique structure, where it has delocalized electrons that can move freely to conduct electricity, but the heat energy is not easily transferred through the material due to weak intermolecular forces.
All metals Conduct:Tin, steel, iron, copper, aluminum, zinc and all other metals conduct electricity very well compared to most other compounds. (These pure metals conduct, but when they are used to form compounds, the result may of may not conduct electricity.)Why metals conduct:With the discoveries in solid state physics of the 20th century we learned that metals are collections of atoms which have somewhat unusually properties of the electrons. In metals the outermost electron (sometimes two) is not specifically associated with that one atom but is free to associate with atoms far and wide. We say these are delocalized electrons. Since the electrons are not attached to specific atoms, it takes very little energy to move them. As a result, any small voltage causes electron flow in a metal.This movement or flow of electrons is called electricity so this is why metals conduct electricity.Aside: Metals are not the only materials that conduct electricity, they just do it especially well.
Alkali metals are the most reactant of all the metals, and conduct electricity very well
