Re: Does electron turn around its own axis
Since an electron may exhibit a magnetic moment even when it does not possess orbital angular momentum, it must possess some internal motion. We call this motion the electron spin and treat it quantum mechanically as another kind of angular momentum. Experimentally, however, all we know is that the electron possesses an intrinsic magnetic moment. The remarkable feature of this intrinsic magnetic moment is that its magnitude and the number of components along a given axis are fixed. A given electron may exhibit only one of two possible components; it may be aligned with the field or against it. Experimentally, or theoretically, this is all we can know about the spin magnetic moment and the spin angular momentum. Hence only one quantum number is required to describe completely the spin properties of a single electron. We shall denote the value of this quantum number by or ¯, the upwards-pointing arrow signifying that the component of the magnetic moment is aligned with the field and the downwards-pointing arrow that this component is opposed to the field.

Talk slowly but think quickly
Spend some time alone
When you realize you've made a mistake, take immediate steps to correct it
BEGIN while others are procrastinating
COMMEND while others are criticizing
PREPARE while others are daydreaming
To handle yourself, use your head; to handle others use your heart.

Re: Does electron turn around its own axis
It's critical.
If someone assume a classical model for an electron in an atom, he (or she) can say, it rotates.
But a classical model may cause very great theorical problems that can't be neglected at all.
So, I think it's not right to say than electron rotates around itself (like a rigid body),
though it may has some intuitional value.
