The presence of electrons in a substance makes it a conductor of electricity.True or False?

true :) electrons, electricity, see the pattern? haha, but that's not why it's true.The presence of electrons in a substance makes it a conductor of electricity.True or False?
True. Just about any substance with a strong enough Voltage applied to it will pass at least a small amount of electrons.The presence of electrons in a substance makes it a conductor of electricity.True or False?
False. Glass has electrons and is a pretty darn poor conductor. See: http://en.wikipedia.org/wiki/Electrical_鈥?/a>
False. Electrons are always present. What counts is their mobility.
It is only half true.


The correct answer is: A substance which contains FREE electrons is a conductor.


An electron is free in a conductor if it can perform a continuous motion inside it, if we generate a potential difference between two points on its surface. In a given conductor that property of a free electron is characterised by its mobility, and the motion is called drift.
False. They need free electrons for them to pass along to the next molicule, meaning an incomlplete number in the outer shell.
False and the answers are total crap. Only when the electrons are promoted into the conduction band like in a metal or a doped semiconductor will an applied electric field make the electrons drift or flow as a current


All 'substances' contain equal amounts of +/-ve electricity..in insulators these charge carriers are tightly bound to their parent atoms and so cannot particip8 in conduction


The guy who does this stuff normally is off somwear..Ah usually only handle the religious hatred an abuse stuff
False. Everything has electrons. The presence of any ions or a dissolved electrolyte will make it a conductor.





EDIT:


However, if it is meant that electrons are flowing through the object (not just contained within the atoms), then it does conduct electricity.
