What will the correct value of spin quantum number for last electron of Na+ ion?
Electronic configuration of $Na^+$ ion is $1s^2,2s^2,2p^6,3s^0$.
I have noticed usually , we take spin quantum number as +1/2 first & then -1/2.
So , like for the above Q:It is for first 3e=+1/2 &...

Excitation of electron in Niels Bohr's atomic model
Professor taught us that an electron gains or looses only those energies which are equal to difference in two energy levels. That is $E_1 + \Delta E = E_2$ or $E_1 + \Delta E = E_3.$
What if we give, ...

What does orbital mean, exactly? [duplicate]
My teacher told me that orbital is the probability distribution data of the electron around nucleus which is amplitude data in a way.
An example of how my teacher actually told what it means involves ...

Does electron mass decrease when it changes its orbit?
I have studied this in my chapter atomic structure that when an electron changes its orbit from lower energy to higher energy state , it does not state in my book that it moves there but that it ...

What does Pauli’s exclusion principle mean in atomic or fundamental way? [closed]
It means is that no electron can have same n , l and $m_l$ but can have two different spin quantum number.
I want to know why is this rule valid?Means there must be some other things happening also ...

Why do subshells and orbitals exist? [closed]
I'm just a curious high school student. Sorry if this sounds dumb.
How exactly did the concept of atomic subshells and orbitals come about? And why exactly are there n-1 subshells and 2l+1 orbitals?

Volume of orbitals
As I was learning about atomic structure, the lecturer made a seemingly dubious claim:
The volume of a p orbital is one-third that of the s orbital. Thus, inter-electronic repulsions are ...
