Metals are good conductors of electricity because :-
1.Metals they have free electrons which contribute in conduction of electricity.
2.Interms of energy bands metals they have no forbidden gape between conduction band and valence band, hence create easy overlapping of electrons from the valence band to conduction band.
3.Metals are ionizing by loosing electrons in their outermost shell so they can give out electrons, as a result of having the habit of conducting electricity because of these free electrons.
4.All metals are solid with great thermal capacity and low impurities, this feature gives all metals to be used as utensils as well as electric wires, since all metals are good conductors of heat and electricity.

Are some metals very poor conductors?
Yes.Heat energy and electrons travel very quickly through metals, allowing the metal to absorb all the heat or cold coming from an object extremely quickly. Proof of this is the fact that an ice cube will melt faster on a sheet of metal than on cardboard.
What is dull brittle and a poor conductor?
Poor conductors of electricity include plastics, woods and gases, in other words, anything that is not a metal. Poor conductors of heat include foam, air and some fabrics, such as felt. Which kind of poor conductor do you mean? Poor conductors/insulators include wood, plasctic, polystyrene foam, fabric, gas or anything that is non-metal. Not necessarily. Nichromium is a combination of the metals nickel and chromium. Is is a fairly poor conductor. Plastic for example is a poor conductor because it is an insulator. Plastic is made up of a substance that dose not allow the flow of electrons. Materials which contains 5 6 or 7 electrons in its outermost shell.
What types of bonds do nonconductors have?
Most nonconductors have covalent bonds. One thing that complicates matters is that some materials with purely covalent bonds do conduct electricity at least to some degree.
What are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Which element has the lowest ionization energy halogens metals non metals or noble gases?
Metals have the least ionization energy
What makes metals good conductors of electricity?
The fact that each atom has at least one electron that's fairly free to move around.
Shinny good conductors malleable?
Metal elements such as iron, aluminium and silver.
Is the best conductors are non-metals?
No. Metals are the best conductors because they have the least resistance. That's why they are used in batteries. Alkaline cells are named so because they use alkali metals in their compositions.
Are some metals very poor conductors?
Yes.Heat energy and electrons travel very quickly through metals, allowing the metal to absorb all the heat or cold coming from an object extremely quickly. Proof of this is the fact that an ice cube will melt faster on a sheet of metal than on cardboard.
Can transitional metals conduct heat?
At least some of them are good heat conductors: Fe, Cu,
Do all nonmetals have some similar physical properties?
Non-metals are much more diverse than metals, however, they all have some similar physical properties. Non-metals are not good conductors of heat or electricity. Solids are usually brittle, non-ductile, not shiny, and at least partially transparent or translucent.
Do sodium and chlorine elements conduct electricity?
Elemental sodium conducts electricity, because it is a metal and all metals are at least moderate conductors of electricity. Elemental chlorine does not conduct electricity, except under very high electric fields that provides sufficient energy to break the chlorine-chlorine bonds or otherwise ionize the chlorine molecules.
If copper is a better conductor of electricity does that mean that it has less resistance?
Yes, the best conductors have the least resistance.
How do metals differ from nonmetals?
Metals usually have characteristic(s) of at least one of the following: luster, shine, malleable, ductile, and conducts electricity. Non metals don't conduct electricity and are usually brittle.
What is the least insulated thing between brown paper and tin foil and bubble wrap and why?
Tin foil, since metals are good conductors/poor insulators.
What are the differentiate of elements and metals?
Some elements are metals; others are not. You are familiar with the general physical properties of common metals such as iron, copper, silver and gold. The other metallic elements are those that have similar physical or chemical properties. There are also some other elements that are similar enough, such as antimony, that they considered to be metals by some people. Metals are typically at least somewhat hard, shiny, able to be pressed or hammered into shape without breaking or cracking (unlike glass, for example) and good conductors of electricity and heat.
Element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat and electricity?
Element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat and electricity are non metals. A metal is an element that has luster, is a good conductor of heat and electricity, is malleable, and is ductile
