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 ...

Is Effective Nuclear Charge the same as Core Electrons?
I'm wondering, what is the difference between the two?
Using the equation for Eff: $\ce{Zeff = Z - S}$
Z being the number of protons in the nucleus and S being inner-shell electrons.
For example:
...

Does restriction on spin in orbits exist?
For a valence electron in Antimony (Sb) with the electron configuration:
$Kr(5s)^2(4d)^{10}(5p)^3$
The 3 valence electrons have the quantum numbers $n=5,l=1,m=1$, resulting in the following ...

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 "...

Few basic questions about ionic bonding and batteries (lead)
I've got a few very very basic questions about ionic bonds and their role in batteries.
My assumptions (correct me if I'm wrong):
Ionic bonds occur between a metal and a non-metal (the non-metal ...
