Why do most objects tend to contain nearly equal numbers of positive and negative charges? What is the difference between an anion and a proton? Explain. Give reasons as to why graphite conducts electricity. Why can graphite conduct electricity?
The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly.Which metals conduct the best?
1) carbon should have no free electron in its structure.Why it can conduct electricity? Ans: Carbon has o kind of structure. i)Diamond钻石& ii)Graphite石墨 i)Diamond钻石--- all carbon atoms are strongly bond tetrahedrally to form a giant covalent neork. There is no free e- ...
Why are metals good conductors of heat and electricity? How do insulators help conductors? Why is foil a good insulator? Why is a good conductor of electricity also a good conductor of heat? Why is cloth a good insulator? Why would electrical engineers or electricians be interested in conducto...
Distilled water is pure and it does not form ions .Whereas rain water contains impurities in it like acid which contains ions and release them when dissolved in water .Hence , electricity is conducted by rain water not by distilled water .
(and former postdoctoral assistant) konstantin novoselov first produced graphene in 2004 by repeatedly peeling away graphite strips with adhesive tape to isolate a single atomic plane. they analyzed its strength, transparency, and conductive properties in a paper for science the same year. super-small...
To explain why ionic solids conduct electricity in the molten state but not in the solid state, we can break down the reasoning into several steps:1. Understanding Ionic Solids: Ionic solids are composed of positively and n
Why are metals good conductors of electricity? Why can graphite conduct electricity? Explain why some ionic compounds are soluble in water. Why are some ionic compounds insoluble? Why are ionic solids poor conductors of heat and electricity although they are composed of charged particles? Explain wh...
Why does the molten sodium chloride conduct electricity, but the solid form of sodium chloride does not? In terms of structure, explain why salt has a higher melting point than sugar. Explain why graphite has a lower melting point than diamond even though both are carbon compounds. ...
A form of substance or material is known as an insulator that retard the transformation or flow of the electron (that denotes the electrical current), or heat from it is known as an insulator. Like, Styrofoam, Plastics, Glass, Rubber, and Fiberglass are some simple examples of ...
