Degeneracy of Orbitals
(Sorry, in advance if my question is silly or low quality but I want to ask this to someone.)
When an electron enters an orbital, it should technically have an electric Field and also magnetic field(...

Refrence on shielding effect vs inter electronic repulsion
Recently I came across a very interesting concept , some scholars were saying that -
Shielding accounts just one component (radial) of interelectronic repulsion not complete repulsion
Who they are -
...

Shielding vs electron-electron repulsion
Example of shielding:
(source)
The last electron in the 6s subshell of $\ce {Cs}$ is shielded from the nucleus by the inner electrons.
Example of electron-electron repulsion:
The electron affinity of ...

What does valence electron mean (in the context of spdf orbitals)?
For a little bit of context, my background is in physics and my understanding of chemistry doesn't go past, say, middle school level. Recently, I decided to self-study chemistry and picked up "...

Electron Energy Levels? [closed]
New to chemistry; In my book it talks about electrons in atoms moving from one energy level or shell to another and denotes this by n. How does this exactly happen, do electrons move to different ...

Nomenclature of This State?
I've read this in a book
It says the state having three parallel spin is called triplet state .
But as far as I know it is determined by "2S+1", from this it comes out to be 4 . Then how it is "...

If d-electrons are such poor shielders, why do trends increase more gradually across the d-block than the s or p-block?
If I understand correctly, the shielding effect of d- (and f-) electrons seems to be much poorer than those of s- and p-electrons, due to the fact that they are less penetrating, have less electron ...
