Is double excitation of nitrogen possible, and would it be able to use it as a central atom in a coordination complex?
I’m 17 and in my 2nd year of high-school (we have it a tad different here in the Czech Republic) and am interested in theoretical chemistry so that’s the explanation of the nature of my question.
So, ...

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 ...

Why is the bond angle of sulphur difluoride greater than that of hydrogen sulphide?
Why is the bond angle of $\ce{SF_2 (98.05^\circ) > SH_2 (92.11^\circ)}$?
Isn't this contradicting Bent's rule or otherwise electron repulsion rule ? Fluorine is more electronegative and hence it ...

AlCl3 and water
While reading Clayden's (et al) Organic Chemistry I stumbled upon a reaction on page 120 that I just fail to wrap my brain around. It describes a reaction of AlCl3 with water and states that, quote, &...

Ionic radius for tetrahedral metal–ligand complexes
The ionic radii for metal–ligand complexes that are in an octahedral coordination are easy to find. I understand that when the $\mathrm{e_g}$ orbital is filled, the ionic radius increases because the ...

Unpaired electrons from magnetic moment
A complex formulated as $\ce{Cs_x[NbCl6]}$ has spin-only magnetic moment $\mu_{s.o}$ of approximately 2 B.M. From this value calculate how many unpaired electrons are present.
Spin-only magnetic ...

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 "...

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(...

Colour of coordination compounds due to d-d transition
Hexaaquanickel(II) is green but tetracyanidonickelate(II) is colourless.
On internet I found two explanations.
One used valence bond theory that claimed there is no excitation of electron in ...
