Do the electrons spin around the nuclues?
If so, do we know the value?
If you use quantum mechanics, then there is no trajectory, but only the probability of find the electron at a given point (in other word it can jump randomly from a measurement to the other)...
"Spin" is not a fortunate term.They mode chaotically and the best we can do about their movement is statistics...
Ahh, here we go again. Good question though...Since this forum is very well prepared, i suggest you read the 'five "socalled"easy pieces post' at the end of this link:https://www.physicsforums.com/showthread.php?t=43685&page=4
