What are the Four Quantum Numbers in Stationary States of the Hydrogen Atom?

AI Thread Summary
The four quantum numbers for the stationary states of the hydrogen atom are n, l, m, and σ. The principal quantum number n indicates the energy level, while the azimuthal quantum number l describes the shape of the orbital. The magnetic quantum number m specifies the orientation of the orbital in space. The spin quantum number σ represents the intrinsic spin of the electron. Understanding these quantum numbers is essential for describing the behavior of electrons in hydrogen.

Q: Explain the meanings of the four quantum numbers, n, l, m, σ which label the stationary states of the electron in the hydrogen atom.

i know what n and m are i can't find anywhere wat l is but i think its radius of orbit, but what is σ?

help would be much appreciated.

but what is σ?
That's the spin quantum number. The other three are spatial quantum numbers.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
