Click For Summary
Quantum numbers are values that describe the unique quantum state of an electron in an atom, including its energy level, angular momentum, and spin. Spin refers to the intrinsic angular momentum of particles, which can be thought of as a form of magnetism at the atomic level. The discussion highlights confusion around these concepts, with requests for simpler explanations and examples. Resources like Wikipedia and HyperPhysics are suggested for further clarification. Understanding these terms is essential for grasping atomic structure and behavior in quantum physics.

Hi there! My physics teacher explained us a Ratherford model of atom and used some terms like "spin" and "quantic number". I'm havin trouble with these terms and maybe anybody can explain me the function of "quantic number" and spinnig and give me a basic example.

I just visited some web sites searching for help, but they have more new terms and i can't understand.

Thank you and sorry for my english.

Spin is magnet in atom - not 2. This no good when polarised.

Hi QuantumBend! I don't understand you. You didn't give a good explanation. Can somebody help me to understand these two terms and give me some basic example?

Thank you.
 
Maybe you can show us the website and say what terms you have trouble with.

'quantic number', maybe you mean "quantum magnetic number"?

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
