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 ...

Half-Filled Shells and Stability explanation [duplicate]
I am reading a book about Advanced Chemistry, and it is discussing the subject of half-filled orbitals.
The book notes that Chromium has an electron structure of $1s^2 2s^2 2p^63s^23p^63d^54s^1$

Energy of electrons in the same subshell
So I have this quote from wikia (it's similar to my lecture pdf file) but I don't fully understand the statement
Although it is commonly stated that all the electrons in a shell have the same ...

Order of the subshells in an electron configuration
According to what my chemistry teacher said, the energy of a subshell is given by the sum of its principal quantum number (n) and its second quantum number (l).
e.g.:
1s = n+l = 1+0 = 1
2s = n+l = 2+...

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 "...

Is it possible create crystalline solvate of electrons?
Okay, I know that this reads ridiculous insane, but one can obtain solvated electrons by adding sodium metal to liquid ammonia solution.
The chemical reaction as written in my inorganic chemistry ...

Why does Sulfur have 12 valence electrons in the Sulfate ion? [duplicate]
So I am completely and utterly confused about why sulfur has $12$ valence electrons. I understand in it's configuration, it has $2$ electrons for the $3\mathrm s$ subshell, and $4$ electrons from its $...

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 ...

By using the magnetic susceptibility, calculate the number of unpaired elections in the complex
I'm having trouble making sense of this answer. I believe I am doing all the steps right, but my main concern is that I am not arriving at a whole number. If my answer is correct, should I just round ...

Is shielding of electrons really best described as shielding or is it really Coulombic repulsion between electrons?
For example, take the 2s electron in lithium - is the reason that it's ionisation energy is lower than would be expected if "shielding" didn't occur at all because the 1s electrons shield the ...
