What exactly is electron spin and intrinsic spin of elementary particles.Any link teaching these concepts from scratch would also be appreciated .
Thnx
Thnx

jtbell said:No, spin is not one of the things that's "opposite" for an antiparticle. For example, an electron can already have its spin either "up" or "down" along a given axis, and likewise for a positron.
Orbital angular momentum falls out when the Schrödinger Wave Equation is solved for a Hydrogen atom.anantchowdhary said:Why is the spin defined in such a way?How do we get the equation?
Electron spin is a fundamental characteristic of an electron, which is a subatomic particle with a negative charge. It is a type of angular momentum that is intrinsic to the electron and does not arise from its motion around the nucleus. Electron spin is one of the quantum numbers that describes an electron's state in an atom.
Intrinsic spin is a fundamental property of elementary particles, which are the building blocks of matter. It refers to the spin that is inherent to a particle and cannot be explained in terms of its motion or composition. Intrinsic spin is quantized, meaning it can only have certain discrete values, and it is a crucial factor in determining the behavior and interactions of particles.
Electron spin and orbital angular momentum are both types of angular momentum, but they describe different aspects of an electron's motion. Orbital angular momentum is associated with the motion of an electron around the nucleus, while electron spin is an intrinsic property of the electron itself. Additionally, electron spin can only have two possible values (up or down), while orbital angular momentum can have multiple values.
Electron spin is important in chemistry because it influences the way electrons behave and interact with each other. The spin of an electron affects its energy level and the bonding between atoms. It also plays a role in determining the magnetic properties of materials. Understanding electron spin is crucial for predicting and explaining chemical reactions and properties of substances.
Yes, the spin of an electron can change, but only under specific circumstances. According to the laws of quantum mechanics, the spin of an electron can flip from "up" to "down" or vice versa when it interacts with other particles or an external magnetic field. However, the spin of an electron is a conserved quantity, meaning that the total spin of a closed system remains constant, so any change in the spin of one electron must be balanced by an opposite change in another particle's spin.
