In atom electron moves in which direction ANTI-CLOCK WISE,CLOCKWISE or IN BOTH DIRECTIONS?

Dear Student,

It's just a matter of perception.As an analogy,consider a spherical tennis ball undergoing a perfectly circular horizontal motion tied to a pole fixed at centre of room.If you see from below it's motion appears to be clockwise(say).Then,from top it will seem to go around in anticlockwise direction.Thus it is just a matter of perception whatever you choose as direction of motion of electron.
