Electrons & Nucleus: Spinning & Value?

In summary, the movement of electrons around the nucleus is not accurately described as spinning. In fact, using quantum mechanics, there is no set trajectory for electrons and their movement can only be understood through probabilities and statistics. The concept of "spin" is not entirely applicable in this case.

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

Related to Electrons & Nucleus: Spinning & Value?

1. How do electrons spin?

Electrons are subatomic particles that have a property known as spin. This spin is not a literal spinning motion, but rather a quantum mechanical property that describes the intrinsic angular momentum of the electron. The direction of spin can either be "up" or "down" and cannot be directly observed.

2. What determines the value of an electron's spin?

The value of an electron's spin is determined by its quantum number, also known as its spin quantum number. This number can have a value of either +1/2 or -1/2, representing the two possible spin orientations of the electron.

3. How is the nucleus related to electron spin?

The nucleus of an atom contains protons and neutrons, which are made up of even smaller particles called quarks. These quarks also have a spin, and their combined spins contribute to the overall spin of the nucleus. This spin can have both positive and negative values.

4. Can electron spin be changed?

Electron spin can be changed through various processes, such as interactions with other particles or exposure to magnetic fields. However, the spin value itself is a fundamental property of the electron and cannot be altered.

5. Why is electron spin important?

Electron spin is important because it is one of the fundamental properties that determines the behavior and interactions of electrons. It plays a crucial role in chemical bonding, magnetic properties, and many other physical phenomena. Understanding electron spin is essential in the fields of physics, chemistry, and materials science.
