Atoms of materials that conduct electricity best tend to be held together by metallic bonds. This is the attraction between positively charged nuclei in metal atoms and the delocalized electrons in the metal.
The free electrons within the metal cause metal to conduct electricity because they drift easily with an applied electric force. All metal conducts electricity.
Metal does indeed conduct heat readily. Metal also conducts electricity. The conductive properties of metal are due to the free electrons in metal atoms that allow for mobile charge.
wood, crystal, diamond, stone, granite
In a foam there is a large gap between the conduction band and the valence of band in the atoms makng up the foam. If any object is to conduct electricity through it the gap between the conduction band amd the valance should be minimun or overlapping so that the electrons in the valance band can go into conduction band and conduct electricity
atoms
Sodium oxide is an insulator because its atoms are held together by ionic bonds, which means that the electrons are tightly bound to the atoms and cannot move freely to conduct electricity. In order for a material to conduct electricity, it needs to have free moving electrons, which is not the case for sodium oxide.
yes....it does
Copper atoms would be held together by metallic bonding, where the electrons are delocalized and allow for the copper atoms to conduct electricity and heat efficiently.
Items conduct electricity by lining up their atoms. much like how things get magnetized. if the atoms line up then electricity can pass between them using them like a bridge. some items, however, cannot line their atoms up (like wood)
o There are some organic compounds that can conduct electricity (organic conductors) salts, solubilized in water or any other solvent that can solubilize them conduct electricity. Molten salts conduct electricity ionized atoms or molecules can conduct electricity
Magnesium is the element that loses 2 atoms when reacting, reacts slowly with water, and can conduct electricity.
The atoms it is made out of do not have 1 or 2 valence electron on the outer shell, so therefore they do not conduct electricity well. Atoms that do have 1 or 2 valence electron on the outer shell, like copper, conduct electricity well.
Metals have lots of electrons that are fairly free to move between the atoms. Those electrons conduct electricity.
Metals have lots of electrons that are fairly free to move between the atoms. Those electrons conduct electricity.
Solutions that do not conduct electricity are typically covalent. In covalent compounds, electrons are shared between atoms rather than transferred, leading to the absence of free ions that can conduct electricity. Ionic compounds, on the other hand, dissociate into ions in solution and are able to conduct electricity.
Diamagnetic substance contains no unpaired electron therefore charge cannot be transferred through moving free electron--there is no free electron. It is however theoretically possible to force the substance to conduct electricity, by setting potential difference extremely high so that bonded electrons are forced to detach from the atoms. At this point, the substance is no longer diamagnetic.
Glass is an insulator because its structure does not contain free electrons that can move freely to conduct electricity. The tightly packed atoms in glass create a strong ionic bond that does not allow for the flow of electric current.
