Metals contain valence electrons and these electrons are free to move from one place to another. In contract, a non conductor -- wood for example - has most of the constituent electrons tightly bound in the atomic and molecular bonds ( which is why wood does not conduct heat either !) This means the electrons can move freely throughout the metallic structure. In a conductor, electric current can flow freely, in an insulator it cannot. Metals form metallic bonds, where unlike in covalent or ionic bonding, electrons are delocalised. No matter how good a conductor the metal in question is, a small amount of energy is lost to friction as electrons make contact with one another. Metals form giant structures in which electrons in the outer shells of the metal atoms are free to move. Pure metals, on the other hand, are superlative conductors because, although their atoms are restrained by structure, their electrons are not… they’re free! The electrons are unrestrained and therefore begin to move around haphazardly when the source imparts kinetic energy into them. Metals have lots of "loose" electrons which can easily move around if a voltage is applied ( and in fact also if heat is applied which is why metals are good conductors of heat as well !!).

Metals are good conductor of electricity and glass in not because in metals electrons are free to move but in glass there is no mobile of free electrons so glass doesnot conduct electricity . The chemical elements that are considered as very good conductors are as follows: Copper Silver Aluminum Gold Nickel Chromium Iron Magnesium Mercury Titanium Molybdenum This is because the free electrons can move throughout the metal. * Not necessary. Metals are good conductors of electricity because of the free electrons that is present in their outer shell that makes them good conductors of electricity. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Therefore, due to the presence of mobile electrons metals can easily conduct electricity. * Though as per Wiedemann–Franz law for metals thermal conductivity (κ) is proportional to the electrical conductivity (σ). Because metals release negative ions which conduct electricity. Electricity is the flow of electrons, and because electrons in metals are delocalised, they can flow through the structure and conduct electricity. Thus, metals are good conductors of heat and electricity because there are free moving atoms in metals that carry both heat and electric current. The metallic bond is the force of attraction between these free electrons and metal ions.Metals are good conductors of electricity and heat. metals are good in conducting electricity because the electrons in metals move freely that can act as a glue that also bonds all of the atoms in the metal together (thats why metals are also malleable and ductile.) This is the most accepted fact that for any thing to transmit electricity by being a good conductor they need more free electrons in their outer shell
This is why electrical wires that carry a lot of current have to be thicker, so electrons have space to move without creating too much heat.
