Quantum mechanics describes the microscopic properties of nature in a regime where classical mechanics no longer applies. It explains phenomena such as the wave-particle duality, quantization of energy, and the uncertainty principle and is generally used in single-body systems. Use the quantum-field-theory tag for the theory of many-body quantum-mechanical systems.

Why does the energy of an atomic orbital depend on the proximity to charges?
I was recently reading about Crystal field theory and especially crystal field splitting in the context of transition metals in coordination complexes. Here is what I think I have understood – or what …

Why 2nd Shell can have 8 electrons?
There is no such thing as a "second orbital". There is a second shell which is "made of" four orbitals which each can hold 2 electrons – this is where the 8 comes from.
So there is no contradiction: E …

How to correctly imagine a quantum particle, what does it look like?
It is tempting to think of an electron as some ball-like1 particle with a definite position and momentum. Unfortunately, such an analogy does not work in quantum mechanics.
In QM, an electron is descr …

How does the uncertainity principle apply in this situation?
This is only an addition to the other excellent answer.
One of my misunderstandings when asking this question was that I thought that the photon does have a specified position at any point in time. Ho …

How does the uncertainity principle apply in this situation?
A common (but, as I think, incomplete) description of the uncertainity principle is the following:
You cannot determine a particle's momentum and position at high accuracy at the same time
It could …

What do atomic orbitals represent in quantum mechanics?
(Disclaimer: I am only a highschool student and have learned the following mostly on my own. If there are any mistakes, please feel free to correct me!)
An atomic orbital represents the probability d …

How exactly do quarks suppress gluon fluctuations?
In both this Veritasium Video and this answer it is said that Quarks suppress gluon fluctuations, thus creating a so-called 'flux tube' which is what binds the gluons together (as explained in both th …

What are Uncertainties in Quantum Mechanics intuitively?
If you look at any macroscopic object such as books, houses etc. (pretty much everything your eyes can see), they have an exact position and momentum. They same is not true for electrons, photons and …

Why doesn't the nucleus have "nucleus-probability cloud"?
As already pointed out in the other answers, nuclei do have a probability cloud. It is only a lot smaller than compared to electrons because the mass of the nucleus (or even a single proton or neutron …

Can a particle have multiple spin states at the same time?
In quantum mechanics, particles are described as wave-like. This means, for example, that an electron or photon does not have a well-defined position before one measures it and causes the wavefunction …

How do delocalized electrons conduct electricity?
I have learned that for a meterial to be conductive, it must contain free charge carriers, in most cases electrons.
Graphite does conduct electricity parellel to its graphene layers, which is due to t …
