Question

Why does electron revolvein anticlockwise direction?

Answer 1

It depends upon how you look it.

Take an example of a wall clock

If you see it from front side ithe hands will revolve in clock wise direction, but when you look it from backside you will notice it will be revolving in anticlockwise direction.

Same is with the electrons present in an atom, if you look if from either front/above or back /below you will it is moving in different movement.

yes movement will be different , but not direction.
