Should we be doing your homework for you MadPi? Shouldn't you be reading your notes or looking it up on the web? If I tell you the answer, will you remember any of it ever again? If you go and find out, you will remember most of it for a long, long time.

Go for it. Make you parents proud!

An electron was the best selling toy for boys in Christmas 1978,one o' the first robot toys.

Don't put that down in yer homework though or ye will get detention.

Sorry MPP,was a biologist at school not a physicist.The rest are right have a google.

An electron is a negatively charged particle found in the atom...thats all I know ha ha and I got a B in Chemistry...

An example is Oxygen i think its O2...the all 2 means that it has 2 electrons...its not a full shell...i realy dont know if thats right..

"a particle, present in all atoms, which has a negative electric charge and is responsible for carrying electricity in solids"....

Hope this link is more helpful -

Anyone from Dounreay able to expand all of our knowledge on this one?

It used to be fairly simple before they tell you about electron Wave–particle duality, I guess for school work knowing that it is a negatively changed particle that orbits around the nucleus of an atom should be good enough.

If you have time after your homework on the electron you might find this site of interest -

For all the Education Systems attempts to expand my knowledge, all I care about is that it flows when I turn the tap on! :lol:

Don't forget that the location of electrons is a probability - they are most likely to be in that orbit most of the time. The theory is that they can be close and distant in fractions of a second.

Don't forget, by looking forward it you change where it is, so there is no hope of ever knowing for sure.
