Why do we only use the principal quantum number to calculate the energy of an electron in an H atom?
According to my high school textbook the energy of an electron in a hydrogen atom is $E = -13.6/n^2~\pu{eV}$, where $n$ is the principal quantum number of the orbital in which the electron is present.

Is the surface electron affinity of (tribasic) sodium- or calcium phosphate higher?
Let's imagine, we have two polycrystalline samples: $\ce{Ca3(PO4)2}$ and $\ce{Na3PO4}$. A free electron is added to both. Some heat is released.
I wanted to check whether my reasoning about this ...

Correct Interpretation of Apparent Charge Transfer Coefficients
Good day guys,
I was looking over some $i$ vs $\eta $ for a redox reaction over a copper cathode, the cell has $\ce{LiBf4}$ in THF as the electrolyte. The main reaction taking place is:
$$\ce{N2 + 6 ...

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, ...

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(...
